From: Arnd Bergmann Date: Fri, 22 Mar 2019 14:19:16 +0000 (+0100) Subject: jfs: fix bogus variable self-initialization X-Git-Tag: for-linus-20190516~85^2 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=a5fdd713d256887b5f012608701149fa939e5645;p=linux-2.6-block.git jfs: fix bogus variable self-initialization A statement was originally added in 2006 to shut up a gcc warning, now but now clang warns about it: fs/jfs/jfs_txnmgr.c:1932:15: error: variable 'pxd' is uninitialized when used within its own initialization [-Werror,-Wuninitialized] pxd_t pxd = pxd; /* truncated extent of xad */ ~~~ ^~~ Modern versions of gcc are fine without the silly assignment, so just drop it. Tested with gcc-4.6 (released 2011), 4.7, 4.8, and 4.9.
