Subject: usign-exec: remove redundant return statements
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=7ec4bb764e1eb58f5d499d3b47f97bfc9a09eb0a;p=oweals%2Fucert.git

usign-exec: remove redundant return statements

All switch() cases were already returning value or exiting. Instead,
move the default case out of the switch to reduce indentation (only
relevant for usign_f()).
