[ Upstream commit 5bb0b194aeee5d5da6881232f4e9989b35957c25 ]
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.
