Uwe Kleine-König a80814fe91 pwm: sti: Simplify probe function using devm functions 
[ Upstream commit 5bb0b194ae ]

Instead of of_clk_get_by_name() use devm_clk_get_prepared() which has
several advantages:

 - Combines getting the clock and a call to clk_prepare(). The latter
   can be dropped from sti_pwm_probe() accordingly.
 - Cares for calling clk_put() which is missing in both probe's error
   path and the remove function.
 - Cares for calling clk_unprepare() which can be dropped from the error
   paths and the remove function. (Note that not all error path got this
   right.)

With additionally using devm_pwmchip_add() instead of pwmchip_add() the
remove callback can be dropped completely. With it the last user of
platform_get_drvdata() goes away and so platform_set_drvdata() can be
dropped from the probe function, too.

Fixes: 378fe115d1 ("pwm: sti: Add new driver for ST's PWM IP")

README 

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.
