Linux kernel source tree
551507e0d0
The runtime PM might be left in error state if one of the callbacks returned an error, e.g. if the (auto)suspend callback failed following a firmware crash. When that happens, any further attempt to acquire or release a power reference will then also fail, making it impossible to do anything else with the GPU. The driver logic will eventually reach the reset code. In pvr_power_reset(), replace pvr_power_get() with a new API pvr_power_get_clear() which also attempts to clear any runtime PM error state if acquiring a power reference is not possible.

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 reStructuredText 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.
