Subject: ASoC: sb16: Simplify snd_sb16dsp_pcm()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=92533f188862fbefe357ada4e4af67b8e730e680;p=openwrt%2Fstaging%2Fblogic.git

ASoC: sb16: Simplify snd_sb16dsp_pcm()

All callers of snd_sb16dsp_pcm() always pass the pcm field of the first
parameter as the last parameter. Simplify the function by moving this inside
the function itself. This makes the code a bit shorter and cleaner.
