sound: oss: remove last sleep_on users
There are three files in oss for which I could not find an easy way to replace interruptible_sleep_on_timeout with a non-racy version. This patch instead just adds a private implementation of the function, now named oss_broken_sleep_on, and changes over the remaining users in sound/oss/ so we can remove the global interface. [fixed coding style warnings by tiwai] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
