Subject: [script] Fix bug of assigning a var to itself (e.g. val = val;)
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=162ff81f0999f0da46b69a31363bf2dec3cbee3e;p=thirdparty%2Fplymouth.git

[script] Fix bug of assigning a var to itself (e.g. val = val;)

Problem was that the var is cleared before being re-assigned, which also clears
the value we were about to write into it.
