Subject: fix(load_fstype): use $1 if $2 is missing
X-Git-Tag: 058~161
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=401158e58c47b2e1278a47b9cd236f501cfe2732;p=thirdparty%2Fdracut.git

fix(load_fstype): use $1 if $2 is missing

Use parameter expansion default value if the second argument is missing.
The current code mistakenly reuses the null second argument.
