Title
drm/amd/display: fix shift-out-of-bounds in CalculateVMAndRowBytes
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix shift-out-of-bounds in CalculateVMAndRowBytes [WHY] When PTEBufferSizeInRequests is zero, UBSAN reports the following warning because dml_log2 returns an unexpected negative value: shift exponent 4294966273 is too large for 32-bit type 'int' [HOW] In the case PTEBufferSizeInRequests is zero, skip the dml_log2() and assign the result directly.
