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. Fixes: c9e3ad6021e5 ("JFS: Get rid of "may be used uninitialized" warnings") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Dave Kleikamp <dave.kleikamp@oracle.com>
