From: Takashi Iwai Date: Mon, 30 Jan 2017 14:58:15 +0000 (+0100) Subject: ALSA: x86: Remove v1 ops and structs X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4812dcc437fbe0ddc2319dae7c31254f57d4ae44;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ALSA: x86: Remove v1 ops and structs The v1 code refers to Medfield/Clovertrail. It's not used at all in the current driver, and probably won't be ever. Let's clean this up, then we can go to the next stage of cleanup tasks.
