Subject: tracefs: Removed unused 'ret' variable in eventfs_iterate()
X-Git-Url: http://git.ipfire.org/index.cgi?a=commitdiff_plain;h=43cec30c44764c4b1401fdeb48bfd18c3fc7eff8;p=thirdparty%2Fkernel%2Flinux.git

tracefs: Removed unused 'ret' variable in eventfs_iterate()

Moving to guard() usage removed the need of using the 'ret' variable but
it wasn't removed. As it was set to zero, the compiler in use didn't warn
(although some compilers do).
