Subject: libfstools: fix find_mount to return device path
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Ffstools.git;a=commitdiff_plain;h=a5076ad9c92895c54eb384b224e7af1a914f1fd9

libfstools: fix find_mount to return device path

So far we were returning mount point which doesn't make sense for a
function that already takes mount point as an argument.
