Subject: dm space map common: remove check for impossible sm_find_free() return value
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c1499a044d7c2bbd9ea3d9c17e17f16595ae6d69;p=linux.git

dm space map common: remove check for impossible sm_find_free() return value

The function sm_find_free() just returns -ENOSPC and 0.
So remove lone caller's check for some other error.
