HID: hid-input: allow input_configured callback return errors

2015-11-05T17:51:50+00:00

When configuring input device via input_configured callback we may
encounter errors (for example input_mt_init_slots() may fail). Instead
of continuing with half-initialized input device let's allow driver
indicate failures.

HID: uclogic: fix limit in uclogic_tablet_enable()

2015-07-29T12:05:15+00:00

The limit should be ARRAY_SIZE(params) (5 elements) here instead of
sizeof(params) (20 bytes).

HID: uclogic: make input_mapping independent of usb

2015-03-16T14:46:47+00:00

No need to retrieve the USB handle in input_mapping() when we already
do that in probe. It also allows to use the quirk without having to
add the product ID matching.

HID: uclogic: actually invert the in-range bit for huion tablets only

2015-03-03T20:31:56+00:00

This hack is only needed for Huion tablets. It does not seem to have
any effect on the other tablets handled by this device right now, but
it's better to check for the product id sooner than discovering that
we have messed up one tablet later.

HID: uclogic: discard the extra Pen input node on Huion tablets

2015-03-03T20:31:55+00:00

Some Huion tablets present 2 HID Pen interfaces. Only one is used, so
we can drop the unused one.

HID: uclogic: apply quirk NO_EMPTY_INPUT

2015-03-03T20:31:55+00:00

NO_EMPTY_INPUT is useful when MULTI_INPUT is set. It prevents to create
empty input nodes that user space does not know what to do with.

It does not seem to be required at the moment, this is just a preventive
patch. This check is only made during the plug of the device, so it does
not hurt to have it.

HID: uclogic: name the input nodes based on their tool

2015-03-03T20:31:55+00:00

We append "Pen", "Pad", "Mouse", "Keyboard", "Consumer Control" or
"System Control" suffix to the appropriate input node to match what
the Wacom driver does and be more convenient for the user to know
which one is which.

Merge the hid-huion driver into hid-uclogic as all the devices supported
by hid-huion are in fact UC-Logic devices.

HID: uclogic: Set quirks from inside the driver

2015-03-03T20:31:54+00:00

Based on a patch from: Nikolai Kondrashov 

Most of the tablets handled by hid-uclogic already use MULTI_INPUT.
For the ones which are not quirked in usbhid/hidquirks, they have a
custom report descriptor which contains only one report per HID
interface. For those tablets HID_QUIRK_MULTI_INPUT is transparent.

According to https://github.com/DIGImend/tablets, the only problematic
tablet currently handled by hid-uclogic is the TWHA60 v3. This tablet
presents different report descriptors from the ones currently quirked.
This is not a problem per se, given that this tablet is not supported
currently in this version (it needs the same command as a Huion to
start forwarding events).

HID: Use module_hid_driver macro

2013-01-03T09:27:31+00:00

Use the new module_hid_driver macro in all HID drivers that have
a simple register/unregister init/exit.

This also converts the hid drivers that test for a failure of
hid_register_driver() and report the failure. Using module_hid_driver
in those drivers removes the failure message.
