[SRU Bionic 0/1] CVE-2022-3303

[Cengiz Can]

[Impact]
It was discovered that the sound subsystem in the Linux kernel contained a race
condition in some situations. A local attacker could use this to cause a denial
of service (system crash).

[Fix]
Cherry picked from linux-5.4.y. Upstream fix does not apply due to error
checking differences.

[Test case]
Compile and boot tested only.

[Potential regression]
Low. Moves an error check a little bit further.
