Re: [PATCH][net-next] qtnfmac: fix uninitialized return code in ret

Not related to your patch but qtnf_map_bar() should be changed not to
return NULL.  When functions return both NULL and error pointers the
NULL is supposed to be a special type of success return.  Here it is
just a fail return where we forgot to set the error code to
ERR_PTR(-ENOMEM).

Thanks for reporting! FWIW it is not a bug, all the checks of pci maps
are in place. Though having both ERR_PTR and NULL in return indeed
looks confusing. We will add a fix in the upcoming cleanup series.
