sound: oss: dmasound: kill SLEEP() macro to avoid race
The use of interruptible_sleep_on_timeout in the dmasound driver is questionable and we want to kill off all sleep_on variants. This replaces the calls with wait_event_interruptible_timeout where possible, to wait for a particular event instead of blocking in a racy way. In the sq_write function, the easiest solution is an open-coded prepare_to_wait loop. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
