Subject: [PATCH] ALSA: Add missing dependency on CONFIG_SND_TIMER
Since the build of PCM timer may be disabled via Kconfig now, each
driver that provides a timer interface needs to set CONFIG_SND_TIMER
explicitly. Otherwise it may get a build error due to missing
symbol.
Fixes: 90bbaf66ee7b ('ALSA: timer: add config item to export PCM timer
disabling for expert')
