[PATCH 8/9] [3.18-stable] staging: unisys: correctly handle return value from queue_delayed_work()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Benjamin Romer <benjamin.romer@xxxxxxxxxx>

Commit f84bd6267d623b49f196d54ba9edc41ff1c4d5e3 upstream

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@xxxxxxxxxxx>.

[arnd: the fix is from 4.4 but needed some minor fixup to adapt
 to context changes]
