Clang generates warnings when one enumerated type is implicitly converted to another.
drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/ppatomfwctrl.c:532:57: warning: implicit conversion from enumeration type 'enum atom_smu11_syspll0_clock_id' to different enumeration type 'BIOS_CLKID' (aka 'enum atom_smu9_syspll0_clock_id') [-Wenum-conversion] if (!pp_atomfwctrl_get_clk_information_by_clkid(hwmgr, SMU11_SYSPLL0_SOCCLK_ID, &frequency))
In this case, that is expected behavior. To make that clear to Clang without explicitly casting these values, change id's type to uint8_t in pp_atomfwctrl_get_clk_information_by_clkid so no conversion happens.
