[ Upstream commit c405f5c15e9f6094f2fa1658e73e56f3058e2122 ] Currently, at91 pmc driver always register the syscore_ops whatever the status of the pmc node that has been found. When set as secure and disabled, the pmc should not be accessed or this will generate abort exceptions. To avoid this, add a check on node availability before registering the syscore operations.

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.
