* Input: wacom - fix compiler warning if !CONFIG_PMGeert Uytterhoeven2014-08-12
| | | | | | | | | | | | | If CONFIG_PM is not set: drivers/hid/wacom_sys.c:1436: warning: ‘wacom_reset_resume’ defined but not used Protect the unused functions by #ifdef CONFIG_PM to fix this.

* Input: wacom - only register once the MODULE_* macrosBenjamin Tissoires2014-08-06
| | | | | | | | | | | | Putting the various MODULE_* makes them appear several times in modinfo because wacom.h is used both in wacom_sys.c and wacom_wac.h. Having the macros near the module declaration makes them appear only once. Add also MODULE_VERSION(DRIVER_VERSION) to export the current version number.

* Input: wacom - remove passing id for wacom_set_reportPrzemo Firszt2014-08-06
| | | | | | | | | | | | Every call of wacom_set_report was passing "id" as a separate parameter and buffer also passed the same information. We can use first u8 of the buffer instead of "id" Signed-off-by: Przemo Firszt <przemo@firszt.eu> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Reviewed-by: Ping Cheng <pingc@wacom.com> Tested-by: Przemo Firszt <przemo@firszt.eu> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
* Input: wacom - check for bluetooth protocol while setting OLEDsBenjamin Tissoires2014-08-06
| | | | | | | | | | | | | Bluetooth Intuos 4 use 1-bit definition while the USB ones use a 4-bits definition. This changes the size of the raw image we receive, and thus the kernel will only accept 1-bit images for Bluetooth and 4-bits for USB.

* Input: wacom - handle Intuos 4 BT in wacom.koBenjamin Tissoires2014-08-06
| | | | | | | | | | | A good point of this change is that now, the Intuos4 bluetooth can handle the different tools (artpen, airbrush, mice), and we get a common interface between USB and BT for accessing the LEDs/OLEDs.

* Input: wacom - prepare the driver to include BT devicesBenjamin Tissoires2014-08-06
| | | | | | | | | | | | Now that wacom is a hid driver, there is no point in having a separate driver for bluetooth devices. This patch prepares the common paths of Bluetooth devices in the common wacom driver. It also adds the sysfs file "speed" used by Bluetooth devices.

* Input: wacom - use a uniq name for the battery deviceBenjamin Tissoires2014-07-25
| | | | | | | | | | | | | | | | | The current implementation uses "wacom_battery" as a generic name for batteries. This prevents us to have two Wacom devices with a battery attached as the power system will complain about the name which is already registered. Use an incremental name for each battery attached.

* Input: wacom - put a flag when the led are initializedBenjamin Tissoires2014-07-25
| | | | | | | | | | | | | | | | | This solves a bug with the wireless receiver: - at plug, the wireless receiver does not know which Wacom device it is connected to, so it does not actually creates all the LEDs - when the tablet connects, wacom->wacom_wac.features.type is set to the proper device so that wacom_wac can understand the packets - when the receiver is unplugged, it detects that a LED should have been created (based on wacom->wacom_wac.features.type) and tries to remove it: crash when removing the sysfs group. Side effect, we can now safely call several times wacom_destroy_leds().
