Subject: staging: unisys: correctly handle return value from queue_delayed_work()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f84bd6267d623b49f196d54ba9edc41ff1c4d5e3;p=linux-beck.git

staging: unisys: correctly handle return value from queue_delayed_work()

Properly handle the return value from queue_delayed_work() - it's a
bool, not an int, so using a less than comparison isn't appropriate.

This mistake was found by David Binderman <dcb314@hotmail.com>.
