[ Upstream commitdbe3ad61dc] A coccicheck run provided information like the following. drivers/gpu/drm/qxl/qxl_kms.c:295:1-7: ERROR: missing iounmap; ioremap on line 178 and execution via conditional on line 185 Generated by: scripts/coccinelle/free/iounmap.cocci A jump target was specified in an if branch. The corresponding function call did not release the desired system resource then. Thus use the label “rom_unmap” instead to fix the exception handling for this function implementation.

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.
