Subject: [PATCH] ALSA: hda - Fixes inverted Conexant GPIO mic mute led
Git-commit: f9ef724d4896763479f3921afd1ee61552fc9836
Patch-mainline: v5.3-rc7
References: bsc#1051510

"enabled" parameter historically referred to the device input or
output, not to the led indicator. After the changes added with the led
helper functions the mic mute led logic refers to the led and not to
the mic input which caused led indicator to be negated.
Fixing logic in cxt_update_gpio_led and updated
cxt_fixup_gpio_mute_hook
Also updated debug messages to ease further debugging if necessary.

Fixes: 184e302b46c9 ("ALSA: hda/conexant - Use the mic-mute LED helper")
