Subject: sound/soc/davinci/davinci-pcm.c: use gen_pool_dma_alloc() in davinci-pcm.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1112b9e2c9c8ae10551a7d34667a6189f971cdba;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sound/soc/davinci/davinci-pcm.c: use gen_pool_dma_alloc() in davinci-pcm.c

Since gen_pool_dma_alloc() is introduced, we implement it to simplify code.
