From: Takashi Iwai Date: Tue, 6 Aug 2019 12:03:56 +0000 (+0200) Subject: ALSA: hda - Don't override global PCM hw info flag X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c1c6c877b0c79fd7e05c931435aa42211eaeebaf;p=openwrt%2Fstaging%2Fblogic.git ALSA: hda - Don't override global PCM hw info flag The commit bfcba288b97f ("ALSA - hda: Add support for link audio time reporting") introduced the conditional PCM hw info setup, but it overwrites the global azx_pcm_hw object. This will cause a problem if any other HD-audio controller, as it'll inherit the same bit flag although another controller doesn't support that feature. Fix the bug by setting the PCM hw info flag locally.
