** Description changed:
[Impact]
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.
cherry-pick from stable
[Test case]
- WIP
+ this is apparently also a CVE so a specific test case probably isn't
+ needed
[Regression potential]
adds just a check for a non-zero value, and this has been upstream for a
while now so should not break a thing
** Changed in: linux (Ubuntu Oracular)
