HID: keep dev_rdesc unmodified and use it for comparisons

2012-10-07T15:35:54+00:00

commit 86e6b77eb7cf9ca2e9c7092b4dfd588f0a3307b6 upstream.

The dev_rdesc member of the hid_device structure is meant to store the original
report descriptor received from the device, but it is currently passed to any
report_fixup method before it is copied to the rdesc member. This patch uses a
temporary buffer to shield dev_rdesc from the side effects of many HID drivers'
report_fixup implementations.

usbhid's hid_post_reset checks the report descriptor currently returned by the
device against a descriptor that may have been modified by a driver's
report_fixup method. That leaves some devices nonfunctional after a resume, with
a "reset_resume error 1" reported. This patch checks the new descriptor against
the unmodified dev_rdesc instead and uses the original, instead of modified,
report size.

HID: Fix logitech-dj: missing Unifying device issue

2012-10-02T17:39:22+00:00

commit 596264082f10dd4a567c43d4526b2f54ac5520bc upstream.

This patch fixes an issue introduced after commit 4ea5454203d991ec
("HID: Fix race condition between driver core and ll-driver").

After that commit, hid-core discards any incoming packet that arrives while
hid driver's probe function is being executed.

This broke the enumeration process of hid-logitech-dj, that must receive
control packets in-band with the mouse and keyboard packets. Discarding mouse
or keyboard data at the very begining is usually fine, but it is not the case
for control packets.

This patch forces a re-enumeration of the paired devices when a packet arrives
that comes from an unknown device.

Based on a patch originally written by Benjamin Tissoires.

HID: hid-multitouch: fix input mode feature command

2012-08-09T15:22:38+00:00

commit 4aceed37e315e8eaa26cb4c8dfd619a32fa24669 upstream.

Zytronic panels shows a new way of setting the Input Mode feature.
This feature is put in the second usage in the HID feature, instead
of the first, as the majority of the multitouch devices.

This patch adds a detection step when the feature is presented to know
where the feature is located in the report. We can then trigger the right
command to the device. This removes the magic number "0" in the function
mt_set_input_mode.
