The snd-firewire-lib.ko has 'amdtp-packet' event of tracepoints. Current
printk format for the event includes 'sizeof(u8)' macro expected to be
extended in compilation time. However, this is not done. As a result,
perf tools cannot parse the event for printing:
$ mount -l -t debugfs
debugfs on /sys/kernel/debug type debugfs (rw,nosuid,nodev,noexec,relatime)
$ cat /sys/kernel/debug/tracing/events/snd_firewire_lib/amdtp_packet/format
...
print fmt: "%02u %04u %04x %04x %02d %03u %02u %03u %02u %01u %02u %s",
REC->second, REC->cycle, REC->src, REC->dest, REC->channel,
REC->payload_quadlets, REC->data_blocks, REC->data_block_counter,
REC->packet_index, REC->irq, REC->index,
__print_array(__get_dynamic_array(cip_header),
__get_dynamic_array_len(cip_header),
sizeof(u8))
$ sudo perf record -e snd_firewire_lib:amdtp_packet
[snd_firewire_lib:amdtp_packet] function sizeof not defined
Error: expected type 5 but read 0
This commit fixes it by obsoleting the macro with actual size.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
