Subject: [PATCH] ALSA: pcm: use helper functions to check whether parameters are determined
Git-commit: b81e5ddb159490270fa2cca4f6682c4452035203
Patch-mainline: v4.13-rc1
References: bsc#1121278
A commit 8bea869c5e56 ("ALSA: PCM midlevel: improve fifo_size handling")
allows drivers to implement calculation of fifo size in parameter
structure. This calculation runs only when two of the other parameters
have single value.
In ALSA PCM core, there're some helper functions for the case. This commit
applies the functions instead of value comparison.
