From 0b57d7602b68f7b2786b2f0e22da39cbd4139a95 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Thu, 8 Dec 2011 08:04:12 -0500 Subject: hwmon: (jz4740) fix signedness bug wait_for_completion_interruptible_timeout() may return negative value. In this case, checking if (t > 0) will return true if t is unsigned.
