mainlining shenanigans
31cd7afa30
Panels drivers store their timings in a device data structure field that is initialized at probe time, either from hardcoded values or from firmware-supplied values. Those timings are then reported through the .get_timings() operation to construct the panel display mode. The panel timings are further modified by the .set_timings() operation, which is called with the timings retrieved by .get_timings(), and mangled by .check_timings(). The latter potentially adjusts the pixel clock only. Conceptually, modifying the panel timings is wrong, as the timings are an intrinsic property of the panel and should thus be fixed. Furthermore, modifying them this way at runtime can result in display modes reported to userspace varying between calls, which is also wrong. There's no actual need to store the mangled pixel clock value in the timings. Don't modify the panel timings in the .set_timings() operation, just forward it to the previous device in the display pipeline.

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.
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.
