From 3a7f8fb1d8c9b6a066b0452cea47c85547c97723 Mon Sep 17 00:00:00 2001 From: Xi Wang Date: Sun, 11 Dec 2011 23:40:56 -0800 Subject: [PATCH] Input: cma3000_d0x - fix signedness bug in cma3000_thread_irq() The error check (intr_status < 0) didn't work because intr_status is a u8. Change its type to signed int.
