Subject: usb-hid: modifiers should generate an event
X-Git-Tag: v0.14.0-rc0~129
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=373dfc441d55fe6619929fd049ab635bdfca9e62;p=thirdparty%2Fqemu.git

usb-hid: modifiers should generate an event

When a modifier key is pressed or released, the USB HID keyboard still
answers NAK, unless another key is also pressed or released.

The patch fixes that by calling usb_hid_changed() when a modifier key
is pressed or released.
