Subject: ASoC: rsnd: INT_ENABLE is needed only Gen2
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=52ea2a79f440740b57925e729a59337414b4c300;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ASoC: rsnd: INT_ENABLE is needed only Gen2

INT_ENABLE is needed only Gen2.
rsnd_mod_write() do nothing on Gen1, but it is confusable.
