If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Takashi Iwai commit 157f0b7f6c0cc0bc88647390006e959e267a0143 upstream. It seems that a workaround for Thinkpad T440s crackling noise can be applied generically to all Thinkpad models: namely, disabling the default alc269 shutup callback. This patch moves it to the existing alc_fixup_tpt440_dock() while also replacing the rest code with another existing alc_fixup_disable_aamix(). It resulted in a good code reduction.
