_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.

BTW in the next revision of patches (just submitted) there is an
additional patch [19/19] that fixes a few problems related to the use
of err.h macros.
