Subject: ASoC: wm_adsp: Split out adsp1 & 2 setup algorithms
X-Git-Tag: v4.2-rc3~17^2~16^2~1^2~9^2~14
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b618a185ac2f0f7c95a8b4a1ab464e923f564028;p=platform%2Fkernel%2Flinux-exynos.git

ASoC: wm_adsp: Split out adsp1 & 2 setup algorithms

The vast majority of the wm_adsp_setup_algs function is case statements
for ADSP1 or ADSP2, this patch splits this out into two separate
functions wm_adsp1_setup_algs and wm_adsp2_setup_algs. The small amount
of shared code between them is factored out into an extra helper
function. This makes the code a lot cleaner.
