Subject: loop: remove redundant pointer inode
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f4354a94e2097fe87a14d47ff502754bb547029a;p=linux.git

loop: remove redundant pointer inode

Pointer inode is being assigned but is never used hence it is redundant
and can be removed.

Cleans up clang warning:
warning: variable 'inode' set but not used [-Wunused-but-set-variable]
