_sr_lookup returns a return code using ERR_PTR so the return value should be checked for errors using IS_ERR. Please note that _sr_lookup checks for NULL parameter internally.? That's clear. I was asking don't you want to return PTR_ERR(sr) instead of -EINVAL.
Oh yes you are correct, that is a good catch. Sorry for my misunderstanding. I caught the same problem at a few other places and I have a patch ready for the error handling code. To be submitted asap.
WBR, Sergei
Thanks! Jean
