clang is confused by our if-else-chain that abruptly exits before a
final else:
drivers/gpu/drm/i915/intel_crt.c:821:11: warning: variable 'status' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
else if (ret < 0)
^~~~~~~
drivers/gpu/drm/i915/intel_crt.c:826:9: note: uninitialized use occurs here
return status;
^~~~~~
drivers/gpu/drm/i915/intel_crt.c:821:7: note: remove the 'if' if its condition is always true
else if (ret < 0)
^~~~~~~~~~~~
drivers/gpu/drm/i915/intel_crt.c:761:12: note: initialize the variable 'status' to silence this warning
int status, ret;
In this case, we can reduce the final else-if clause to an unconditional
else.

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.
