Subject: ASoC: Make snd_soc_dapm_kcontrol_codec() inline
X-Git-Tag: firefly_0821_release~176^2~1862^2~14^2~11^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=6b5b042d4c675cb9d3446a1cdcaca98e715ba812;p=firefly-linux-kernel-4.4.55.git

ASoC: Make snd_soc_dapm_kcontrol_codec() inline

snd_soc_dapm_kcontrol_codec() is a extremely simple function and inlining it
typically results in less code than necessary for calling the non-inlined
version of the function.
