clang reportes this error
drivers/gpu/drm/rockchip/rockchip_drm_vop2.c:2322:8: error:
variable 'possible_crtcs' is used uninitialized whenever 'if'
condition is false [-Werror,-Wsometimes-uninitialized]
if (vp) {
^~
drivers/gpu/drm/rockchip/rockchip_drm_vop2.c:2336:36: note:
uninitialized use occurs here
ret = vop2_plane_init(vop2, win, possible_crtcs);
^~~~~~~~~~~~~~
drivers/gpu/drm/rockchip/rockchip_drm_vop2.c:2322:4:
note: remove the 'if' if its condition is always true
if (vp) {
^~~~~~~~
The else-statement changes the win->type to OVERLAY without setting the
possible_crtcs variable. Rework the block, initialize possible_crtcs to
0 to remove the else-statement. Split the else-if-statement out to its
own if-statement so the OVERLAY check will catch when the win-type has
been changed.

README
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.
