If ge_b850v3_lvds_init() does not allocate memory for ge_b850v3_lvds_ptr,
then a null pointer dereference is accessed.
The patch adds checking of the return value of ge_b850v3_lvds_init().

This patch implements WA for AM65xx erratum i2000, which causes YUV
formats to show wrong colors.
An earlier patch removed a partial WA:
a8d9d7da15 ("drm/tidss: remove AM65x PG1 YUV erratum code")
The patch explains the reasoning for removal. The change in plans has
been that it has become clear that there are and will be users for PG1
SoCs and as such it's good to implement the WA for PG1s.
This patch adds the WA back so that it is only used on SR1.0 (which is
the new name for PG1). The previous WA code didn't check the SoC
revision, which this patch does.

Finalize he conversion of GMA500 to use only GPIO descriptors.
The GPIO look-up-table is associated with the device directly
in the GMA500 Medfield chip driver since no explicit platform
type device (such as in x86/platform/intel-mid) exists: the
GMA500 probes directly from the PCI device. Apparently GPIOs
128 and 34 are used on all of these so just go ahead and

"A few differerent things in here.
Seems like syzbot got some more io_uring bits wired up, and we got a
handful of reports and the associated fixes are in here.
General fixes too, and a lot of them marked for stable.
Lastly, a bit of fallout from the async buffered reads, where we now
more easily trigger short reads. Some applications don't really like
that, so the io_read() code now handles short reads internally, and
got a cleanup along the way so that it's now easier to read (and
documented). We're now passing tests that failed before"

I collected a single fix during the merge window: we managed to break the early
trap setup on !MMU, this patch fixes it.
The power keeps going on here so I haven't have a chance to give this the
testing I usually would, but I don't have a Kendryte anyway so I doubt I'd pick
up anything subtle even if I was to test. The patch seems pretty safe and it's
still early, so I don't see any reason to let it sit around.
It's fairly late so if it misses the merge window that's not a big deal. I'll
definately have stuff for next week, so I'll just start from whenever this
lands.

Pull arch/sh updates from Rich Felker:
"Cleanup, SECCOMP_FILTER support, message printing fixes, and other
changes to arch/sh"
* tag 'sh-for-5.9' of git://git.libc.org/linux-sh: (34 commits)
sh: landisk: Add missing initialization of sh_io_port_base

...
One case was missed in the short IO retry handling, and that's hitting
-EAGAIN on a blocking attempt read (eg from io-wq context). This is a
problem on sockets that are marked as non-blocking when created, they
don't carry any REQ_F_NOWAIT information to help us terminate them
instead of perpetually retrying.
Fixes: 227c0c9673 ("io_uring: internally retry short reads")

There's a bit of confusion on the matching pairs of poll vs double poll,
depending on if the request is a pure poll (IORING_OP_POLL_ADD) or
poll driven retry.
Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().
Finally ensure that wait->private is cleared once the double poll handler
has run, so that remove knows it's already been seen.

Fixes: 18bceab101 ("io_uring: allow POLL_ADD with double poll_wait() users")
Signed-off-by: Jens Axboe <axboe@kernel.dk>
Fixes:
- Fixes for 'perf bench numa'.
- Always memset source before memcpy in 'perf bench mem'.
- Quote CC and CXX for their arguments to fix build in environments using
those variables to pass more than just the compiler names.
- Fix module symbol processing, addressing regression detected via "perf test".
- Allow multiple probes in record+script_probe_vfs_getname.sh 'perf test' entry.
Improvements:
- Add script to autogenerate socket family name id->string table from copy of
kernel header, used so far in 'perf trace'.
- 'perf ftrace' improvements to provide similar options for this utility so
that one can go from 'perf record', 'perf trace', etc to 'perf ftrace' just
by changing the name of the subcommand.
- Prefer new "sched:sched_waking" trace event when it exists in 'perf sched'
post processing.
- Update POWER9 metrics to utilize other metrics.
- Fall back to querying debuginfod if debuginfo not found locally.
Miscellaneous:
- Sync various kvm headers with kernel sources.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
fedora:rawhide with python3 and gcc 10.1.1-2 is failing (10.1.1-1 on fedora:32
works), fixes will be provided soon.
clearlinux:latest is failing on libbpf, there is a fix already in the bpf tree.

Pull more perf tools updates from Arnaldo Carvalho de Melo:
"Fixes:
- Fixes for 'perf bench numa'.
- Always memset source before memcpy in 'perf bench mem'.
- Quote CC and CXX for their arguments to fix build in environments
using those variables to pass more than just the compiler names.
- Fix module symbol processing, addressing regression detected via
"perf test".
- Allow multiple probes in record+script_probe_vfs_getname.sh 'perf
test' entry.
Improvements:
- Add script to autogenerate socket family name id->string table from
copy of kernel header, used so far in 'perf trace'.
- 'perf ftrace' improvements to provide similar options for this
utility so that one can go from 'perf record', 'perf trace', etc to
'perf ftrace' just by changing the name of the subcommand.
- Prefer new "sched:sched_waking" trace event when it exists in 'perf
sched' post processing.
- Update POWER9 metrics to utilize other metrics.
- Fall back to querying debuginfod if debuginfo not found locally.
Miscellaneous:
- Sync various kvm headers with kernel sources"
