[PATCH 0/3] selftests: ALSA: pcmtest: Test error injection and pause

[HyeongJun An <sammiee5311@gmail.com>]

The pcmtest driver can return errors from its PCM callbacks and
supports pause, but the selftest covers neither. This series adds tests
for both.

Patch 1 moves the capture data check into a helper, so patch 3 can
reuse it. Patch 2 tests each inject_*_err parameter. Patch 3 tests
pausing a capture stream.

Tested on x86_64 with the sound/for-next driver, built for a 6.17 host.
All 10 tests pass in three runs. To check that the pause test catches
real bugs, I loaded two broken drivers. One keeps running on PAUSE_PUSH.
The other restarts the data on PAUSE_RELEASE. Only capture_pause fails
on each.
