Linux kernel source tree
88051f55de
The code is complicated because we want to check if the GDSC is enabled or disabled based on different bits in different registers while the GDSC hardware is slightly different across chips. Furthermore, we poll the status of the enable or disable state by checking if the gdsc is enabled or not, and then comparing that to if the gdsc is being enabled or disabled. Let's push all that into one function, so we can ask if the status matches what we want, either on or off. Then the call site can just ask that question, and the logic to check that state can simply return yes or no, and not 1 or 0 or 0 or 1 depending on if we're enabling or disabling respectively.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
