Some devices have the overrides of spec->init_amp at HDA_FIXUP_ACT_PROBE just because alc_ssid_check() gives the false-positive values from the SSID. For more consistent behavior, define the logic in the following way: - Define ALC_INIT_UNDEFINED as the default value before calling alc_ssid_check() - Each fixup may set up spec->init_amp with another value at HDA_FIXUP_ACT_PRE_PROBE - At detection, check whether spec->init_amp is ALC_INIT_UNDEFINED or not; if it's different, we skip the detection Also, it turned out that ASUS TX300 requires the spec->init_amp override, too; currently it ignores the GPIO bits implicitly by its static init verb, but this will be changed in the later patchset.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
