Subject: ALSA: x86: Drop global hlpe_state
X-Git-Tag: v4.11-rc1~100^2~10^2~34^2~39
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=055610b002c1066b8ca1919b8d051d80c9e2d86e;p=karo-tx-linux.git

ALSA: x86: Drop global hlpe_state

Now it's the turn to drop the global hlpe_state variable.  It can be
gracefully embedded in hdmi_lpe_audio_ctx struct.
