Subject: ver_linux: Move stderr redirection from function parameter to function body
X-Git-Tag: v4.18-rc1~135^2~17
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4169bc43dbdd6c08436a7d794844b1f09a6367ae;p=thirdparty%2Fkernel%2Flinux.git

ver_linux: Move stderr redirection from function parameter to function body

Remove stderr redirection to stdout from all the parameters to the
version() function, and put it with the body of the version() function
instead.
This improves code readability.
