From: Takashi Iwai Date: Mon, 21 Mar 2016 11:36:44 +0000 (+0100) Subject: ALSA: hda - Apply AMP fix in hdmi_setup_audio_infoframe() generically X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=44bb6d0c3f690e60670517859925417bd7c42a22;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ALSA: hda - Apply AMP fix in hdmi_setup_audio_infoframe() generically The need for reprogramming the AMP mute bit at each audio info frame setup isn't always specific to Intel chips. It's safer to set it generically for all codecs with the amp bit, as this verb execution itself isn't too much load. This eliminates one usage of is_haswell_plus() macro, after all.
