From: Lars-Peter Clausen Date: Sun, 18 Oct 2015 13:39:30 +0000 (+0200) Subject: ASoC: bytcr_rt5640: Use snd_pcm_hw_constraint_single() X-Git-Tag: firefly_0821_release~176^2~581^2~31^2~12^2~3 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d0a1b6607480e9ded3df22d09ff77bc55db586f7;p=firefly-linux-kernel-4.4.55.git ASoC: bytcr_rt5640: Use snd_pcm_hw_constraint_single() Use the new snd_pcm_hw_constraint_single() helper function rather than installing a list constraint with a single value. Since snd_pcm_hw_constraint_single() sets a static constraint while snd_pcm_hw_constraint_list() sets a dynamic constraint the former is slightly more efficient and it also needs less code.
