clang static analysis reports this error
amdgpu_smu.c:2289:9: warning: Called function pointer
is null (null dereference)
return smu->ppt_funcs->emit_clk_levels(
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
There is a logic error in the earlier check of
emit_clk_levels. The error value is set to
the ret variable but ret is never used. Return
directly and remove the unneeded ret variable.
Fixes: 5d64f9bbb628 ("amdgpu/pm: Implement new API function "emit" that accepts
buffer base and write offset")
