357 int amdgpumcasmugetmcaentry(struct amdgpudevice *adev, enum amdgpumcaerrortype type, 358 int idx, struct mcabankentry *entry) 359 { 360 const struct amdgpumcasmufuncs *mcafuncs = adev->mca.mcafuncs; 361 int count; 362 363 switch (type) { 364 case AMDGPUMCAERRORTYPEUE: 365 count = mcafuncs->maxue_count;
mca_funcs is dereferenced here.
366 break; 367 case AMDGPUMCAERRORTYPECE: 368 count = mcafuncs->maxce_count;
