2022-07-07drm/radeon: avoid bogus "vram limit (0) must be a power of 2" warningMateusz Jończyk1-1/+1
I was getting the following message on boot on Linux 5.19-rc5: radeon 0000:01:05.0: vram limit (0) must be a power of 2 (I didn't use any radeon.vramlimit commandline parameter). This is caused by commit 8c2d34eb53b9 ("drm/radeon: use kernel is_power_of_2 rather than local version") which removed radeon_check_pot_argument() and converted its users to is_power_of_2(). The two functions differ in its handling of 0, which is the default value of radeon_vram_limit: radeon_check_pot_argument() "incorrectly" considered it a power of 2, while is_power_of_2() does not. An appropriate conditional silences the warning message. It is not necessary to add a similar test to other callers of is_power_of_2() in radeon_device.c. The matching commit in amdgpu: commit 761175078466 ("drm/amdgpu: use kernel is_power_of_2 rather than local version") is unaffected by this bug. Tested on Radeon HD 3200. Not ccing stable, this is not serious enough.
