Subject[PATCH 18/25] staging: lustre: libcfs: clear up failure patch in cfs_cpt_*_print
Date
From: Dmitry Eremin <dmitry.eremin@intel.com>

Currently both cfs_cpt_table_print() and cfs_cpt_distance_print()
handle the error path in a confusing way. Simplify it so it just
returns E2BIG on failure instead of testing rc value before
exiting.
