ALSA: aoa: Skip devices with no codecs in i2sbus_resume()

Browse source

[ Upstream commit fd7df93013 ]

In i2sbus_resume(), skip devices with an empty codec list, which avoids
using an uninitialized 'sysclock_factor' in the 32-bit format path in
i2sbus_pcm_prepare().

In i2sbus_pcm_prepare(), replace two list_for_each_entry() loops with a
single list_first_entry() now that the codec list is guaranteed to be
non-empty by all callers.
