[alsa-devel] [PATCH 03/18] ALSA: lx6464es: Use snd_pcm_hw_constraint_single()

[Lars-Peter Clausen]

Use the new snd_pcm_hw_constraint_single() helper function instead of
calling snd_pcm_hw_constraint_minmax() with the same value for min and max
to install a constraint that limits the possible configuration values to a
single value. Using snd_pcm_hw_constraint_single() makes the indented
result clearer.
