Uwe Kleine-König 0ce06035ea crypto: stm32 - Properly handle pm_runtime_get failing
[ Upstream commit aec48805163338f8413118796c1dd035661b9140 ]

If pm_runtime_get() (disguised as pm_runtime_resume_and_get()) fails, this
means the clk wasn't prepared and enabled. Returning early in this case
however is wrong as then the following resource frees are skipped and this
is never catched up. So do all the cleanups but clk_disable_unprepare().

Also don't emit a warning, as stm32_hash_runtime_resume() already emitted
one.

Note that the return value of stm32_hash_remove() is mostly ignored by
the device core. The only effect of returning zero instead of an error
value is to suppress another warning in platform_remove(). So return 0
even if pm_runtime_resume_and_get() failed.

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.
