HID: debug: improve hid_debug_event()

2015-11-26T23:02:59+00:00

The code in hid_debug_event() causes horrible code generation. First,
we do a strlen() call for every byte we copy (we're doing a store to
global memory, so gcc has no way of proving that strlen(buf) doesn't
change). Second, since both i, list->tail and HID_DEBUG_BUFSIZE have
signed type, the modulo computation has to take into account the
possibility that list->tail+i is negative, so it's not just a simple
and.

Fix the former by simply not doing strlen() at all (we have to load
buf[i] anyway, so testing it is almost free) and the latter by
changing i to unsigned. This cuts 29% (69 bytes) of the size of the
function.

HID: debug: fix error handling in hid_debug_events_read()

2015-04-10T15:32:21+00:00

In the unlikely case of hdev vanishing while hid_debug_events_read() was
sleeping, we can't really break out of the case switch as with other cases,
as on the way out we'll try to remove ourselves from the hdev waitqueue.

Fix this by taking a shortcut exit path and avoiding cleanup that doesn't
make sense in case hdev doesn't exist any more anyway.

HID: multitouch: Add support for button type usage

2015-03-12T04:04:13+00:00

According to [1], Windows Precision Touchpad devices must supply
a button type usage in the device capabilities feature report. A
value of 0 indicates that the device contains a depressible
button (i.e. it's a click-pad) whereas a value of 1 indicates
a non-depressible button. Add support for this usage and set
INPUT_PROP_BUTTONPAD on the touchpad input device whenever a
depressible button is present.
