Here are a number of small staging and IIO driver fixes for 5.6-rc7
Nothing major here, just resolutions for some reported problems:
- iio bugfixes for a number of different drivers
- greybus loopback_test fixes
- wfx driver fixes
All of these have been in linux-next with no reported issues.

Newer GCC warns about possible truncations of two generated path names as
we're concatenating the configurable sysfs and debugfs path prefixes
with a filename and placing the results in buffers of the same size as
the maximum length of the prefixes.
snprintf(d->name, MAX_STR_LEN, "gb_loopback%u", dev_id);
snprintf(d->sysfs_entry, MAX_SYSFS_PATH, "%s%s/",
t->sysfs_prefix, d->name);
snprintf(d->debugfs_entry, MAX_SYSFS_PATH, "%sraw_latency_%s",
t->debugfs_prefix, d->name);
Fix this by separating the maximum path length from the maximum prefix
length and reducing the latter enough to fit the generated strings.
Note that we also need to reduce the device-name buffer size as GCC
isn't smart enough to figure out that we ever only used MAX_STR_LEN
bytes of it.

Newer GCC warns about a possible truncation of a generated sysfs path
name as we're concatenating a directory path with a file name and
placing the result in a buffer that is half the size of the maximum
length of the directory path (which is user controlled).

Here is the big staging/iio driver patches for 5.6-rc1
Included in here are:
- lots of new IIO drivers and updates for that subsystem
- the usual huge quantity of minor cleanups for staging drivers
- removal of the following staging drivers:
- isdn/avm
- isdn/gigaset
- isdn/hysdn
- octeon-usb
- octeon ethernet
Overall we deleted far more lines than we added, removing over 40k of
old and obsolete driver code.
All of these changes have been in linux-next for a while with no
reported issues.

The functions link_destroy and link_release are both deleting list items.
link_release, however, does not check whether a certain link has already
been deleted from the list by function link_destroy. By fixing this
this patch prevents a kernel crash when removing the configuration
directory of a link that already has been destroyed.

This patch makes the adapter drivers use their own device structures
when registering a most interface with the core module.
With this the module that actually operates the physical device is the
owner of the device.

Remove 'fs_func struct' and change indirect calls to direct calls.
The following issues are described in exfat's TODO.
> Create helper function for exfat_set_entry_time () and
> exfat_set_entry_type () because it's sort of ugly to be calling the same functionn directly and other code calling through the fs_func struc ponters ...
The fs_func struct was used for switching the helper functions of fat16/fat32/exfat.
Now, it has lost the role of switching, just making the code less readable.

In wilc_wlan_handle_txq(), mutex unlock was called without acquiring
it. Also error code for full VMM condition was incorrect as discussed in
[1]. Now used a proper code to indicate VMM is full, for which transfer
to VMM is required again. 'wilc_wlan_handle_txq()' should be called
again if the VMM space was full earlier or otherwise based on
'txq_event' signal.

The Imgu acronyms are moved from header file into Document by previous
commit b8726aea59 ("media: ipu3: update meta format documentation"), so
the item can be removed from TODO list now.

This reverts commit e878742c83.
Imgu should still keep the capability and flexibility to allow user to
run 2 video pipes, as the user may use the video pipe to capture still
frames with less system load and power than still pipe.

The RK3399 variant does not have postproc_regs declared,
this can cause a NULL pointer dereference trying to decode:
[ 89.331359] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000
[ 89.352804] Call trace:

Fix this by adding a NULL check in hantro_postproc_enable/disable.

Following the device's documentation guidance, reading a packet from the
device or writing a packet to it must be atomic. Previously, only
reading device's vacancy (before writing on it) or occupancy (before
reading from it) was locked. Hence, effectively reading the packet or
writing the packet wasn't locked at all. However, reading a packet (and
writing one, to a lesser extent) requires to read 3 different registers
in a specific order, without missing one or else we should reset the
device.
This patch fixes the device's locking mechanism on the FIFO character
device. As the device was using copy_from_user() and copy_to_user(), we
need to replace spinlocks with mutexes.

The firmware now uses throughput enhancement code by default for SPI so
remove the previous implementation as its not used anymore. Removed the
use of 'has_thrpt_enh' element as its always true.
