Subject: Don't get iw version from git if there is no .git/
X-Git-Tag: v3.13~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b0dc6755d97e5add4ef23266a30fb8bdee5ca129;p=thirdparty%2Fiw.git

Don't get iw version from git if there is no .git/

The version.sh script should only try to get the version from git if the
source actually resides in a git repository, i.e. .git/ exists. Doing
otherwise in a non-git source repo results in git ascending until it
finds a .git directory, which will cause problems in some source-based
distributions ( https://bugs.gentoo.org/show_bug.cgi?id=482334 ).
