From: Matthias Kaehlcke mka@chromium.org
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.
