ASoC: simple-card-utils: fix PCM constraint error check
[ Upstream commit 635071f5fee31550e921644b2becc42b3ff1036c ] The code in asoc_simple_startup was treating any non-zero return from snd_pcm_hw_constraint_minmax as an error, when this can return 1 in some normal cases and only negative values indicate an error. When this happened, it caused asoc_simple_startup to disable the clocks it just enabled and return 1, which was not treated as an error by the calling code which only checks for negative return values. Then when the PCM is eventually shut down, it causes the clock framework to complain about disabling clocks that were not enabled. Fix the check for snd_pcm_hw_constraint_minmax return value to only treat negative values as an 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.
