Descriptions

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add check for granularity in dml ceil/floor helpers [Why]
Wrapper functions for dcn_bw_ceil2() and dcn_bw_floor2()
should check for granularity is non zero to avoid assert and
divide-by-zero error in dcn_bw_ functions. [How]
Add check for granularity 0. (cherry picked from commit f6e09701c3eb2ccb8cb0518e0b67f1c69742a4ec)
