We'd previously moved the pipe_lock spinlock to the hwpipe struct. Bring it back to mdp5_plane. We will need this because an mdp5_plane in the future could comprise of 2 hw pipes. It makes more sense to have a single lock to protect the registers for the hw pipes used by a plane, rather than trying to take individual locks per hwpipe when committing a configuration.

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.
