ALSA: sb: Convert timers to use timer_setup()
In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly. [Re-use the existing chip->midi_substream_output instead of assigning a new field to struct snd_sb -- tiwai] Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
