From 379d7cfa9bcae3b89299fdcb135ec0e2810e97bc Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 29 Sep 2015 16:02:29 -0700 Subject: Input: ff-core - silence an underflow warning My static checker complains that "value" comes from the user in evdev_do_ioctl() and we check that it's not too large here but we don't check that it's negative. It's harmless because the ->set_gain() and ->set_autocenter() functions truncate it to a valid u16 value, but we may as well fix it just to make the static checker happy.
