Fair One. I will look to change the name. Also, May be I could use only 'priv' as argument and extract/use 'baseaddr' and 'stat' in the function definition itself. > > > @@ -372,10 +393,12 @@ static int synps_edac_init_csrows(struct > mem_ctl_info *mci) > > for (j = 0; j < csi->nr_channels; j++) { > > dimm = csi->channels[j]->dimm; > > dimm->edac_mode = EDAC_FLAG_SECDED; > > - dimm->mtype = synps_edac_get_mtype(priv- > >baseaddr); > > + dimm->mtype = priv->p_data- > >synps_edac_get_mtype( > > + priv->baseaddr); > > Ditto - that trailing opening brace at the end is just yucky.

Okay. I will correct it in v4. Thanks, Manish Narani
