This is a quick and low risk fix. Those APIs which are exposed to other IPs or to support sysfs/hwmon interfaces or DAL will have lock protection.

2019-06-24drm/amdgpu: fix modprobe failure for uvd_4/5/6Hawking Zhang
For uvd_4/5/6, amdgpu driver will only power on them when there are jobs assigned to decode/enc rings.uvd_4/5/6 dpm was broken since amdgpu_dpm_set_powergating_by_smu only covers gfx block. The change would add more IP block support in amdgpu_dpm_set_powergating_by_smu For GFX/UVD/VCN/VCE, if the new SMU driver is supported, invoke new power gate helper function smu_dpm_set_power_gate, otherwise, fallback to legacy powerplay helper function pp_set_powergating_by_smu. For other IP blocks always invoke legacy powerplay helper function.

2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;
