Subject: HID: reject input outside logical range only if null state is set
From: "Valtteri Heikkilä" <rnd@xxxxxx>
[ Upstream commit 3f3752705dbd50b66b66ad7b4d54fe33d2f746ed ]
This patch fixes an issue in drivers/hid/hid-input.c where USB HID
control null state flag is not checked upon rejecting inputs outside
logical minimum-maximum range. The check should be made according to USB
HID specification 1.11, section 6.2.2.5, p.31. The fix will resolve
issues with some game controllers, such as:
