[PATCH 4.9 031/102] btrfs: Remove extra parentheses from condition in copy_items()
From: Greg Kroah-Hartman
Date: Fri Apr 06 2018 - 10:44:24 EST
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthias Kaehlcke <mka@xxxxxxxxxxxx>
commit 0dde10bed2c44a4024eb446cc72fe4e0cb97ec06 upstream.
There is no need for the extra pair of parentheses, remove it. This
fixes the following warning when building with clang:
fs/btrfs/tree-log.c:3694:10: warning: equality comparison with extraneous
parentheses [-Wparentheses-equality]
if ((i == (nr - 1)))
~~^~~~~~~~~~~
Also remove the unnecessary parentheses around the substraction.
