[KJ] [PATCH 13/20] sound/gus_pcm: remove

[Nishanth Aravamudan]

[-- Attachment #1: Type: text/plain, Size: 1170 bytes --]

Hello,

Please consider applying.

Description: Replace deprecated interruptible_sleep_on_timeout() with
wait_event_timeout(). Code is not identical, as the current sleeping system is 1
jiffy at a time checking atomic_read()'s return every iteration. Patch is
compile-tested.

Thanks, I applied this one.

The other fixes for sound/seq/* stuff are not applied.  Instead, I
modified the code to use wait_event*() properly.
Now all sleep_on*() are gone from ALSA tree.
