In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Assign normalizedpixclk when color depth = 14
[WHY & HOW] A warning message "WARNING: CPU: 4 PID: 459 at ... /dcresource.c:3397 calculatephypixclks+0xef/0x100 [amdgpu]" occurs because the displaycolordepth == COLORDEPTH141414 is not handled. This is observed in Radeon RX 6600 XT.
It is fixed by assigning pix_clk * (14 * 3) / 24 - same as the rests.
Also fixes the indentation in getnormpix_clk.
(cherry picked from commit 274a87eb389f58eddcbc5659ab0b180b37e92775)
