Subject: ALSA: hda - Clean up cxt5066 port-D handling & co
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a3de8ab8853c5a14e881f0a01aa31e3dc87fc304;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

ALSA: hda - Clean up cxt5066 port-D handling & co

Instead of hard-coded magic numbers, properly define and use macros
for improve the readability.  Also, dell_automute is handled samely
as thinkpad, since it also sets port_d_mode, too.
