Jihed Chaibi da52add2b8 ASoC: adau1372: Fix clock leak on PLL lock failure 
[ Upstream commit bfe6a264ef ]

adau1372_enable_pll() was a void function that logged a dev_err() on
PLL lock timeout but did not propagate the error. As a result,
adau1372_set_power() would continue with adau1372->enabled set to true
despite the PLL being unlocked, and the mclk left enabled with no
corresponding disable on the error path.

Convert adau1372_enable_pll() to return int, using -ETIMEDOUT on lock
timeout and propagating regmap errors directly. In adau1372_set_power(),
check the return value and unwind in reverse order: restore regcache to
cache-only mode, reassert GPIO power-down, and disable the clock before
returning the error.

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.

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.
