mainlining shenanigans
9cbaf4d969
The function offb_destroy did not deallocate the color map leaving some
memory around after destruction. Call the color map deallocate function to
remove the memory leak.
Handle another case where color map should have been deallocated during an
error code path.
Fix memory leaks reported by kmemleak:

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.
