Input: wacom - fix error path in wacom_probe()

2011-02-11T09:01:15+00:00

If we fail to retrieve HID descriptor we need to free allocated URB so jump to proper label to do that. Signed-off-by: Alexander Strakh Acked-by: Henrik Rydberg Signed-off-by: Dmitry Torokhov

Input: wacom - properly enable runtime PM

2010-10-18T04:20:46+00:00

We need to always call usb_autopm_put_interface() in wacom_open(), not only when initialization fails, otherwise the device will be marked as PM-busy and will never be put in suspended state. Based on patch by Oliver Neukum. Acked-by: Oliver Neukum Signed-off-by: Dmitry Torokhov

Input: wacom - fix runtime PM related deadlock

2010-10-05T05:36:41+00:00

When runtime PM is enabled by default for input devices, X hangs in wacom open: [] mutex_lock+0x1a/0x40 [] wacom_resume+0x3b/0x90 [wacom] [] usb_resume_interface+0xd2/0x190 [] usb_resume_both+0x6d/0x110 [] usb_runtime_resume+0x24/0x40 [] __pm_runtime_resume+0x26f/0x450 [] __pm_runtime_resume+0x1da/0x450 [] pm_runtime_resume+0x2a/0x50 [] usb_autopm_get_interface+0x26/0x60 [] wacom_open+0x36/0x90 [wacom] wacom_open() takes wacom->lock and calls usb_autopm_get_interface(), which in turn calls wacom_resume() which tries to acquire the lock again. The fix is to call usb_autopm_get_interface() first, before we take the lock. Since we do not do usb_autopm_put_interface() until wacom_close() is called runtime PM is effectively disabled for the driver, however changing it now would risk regressions so the complete fix will have to wait till the next merge window.

Input: wacom - request tablet data for Bamboo Pens

2010-09-12T07:13:23+00:00

Bamboo P&T need to use second form of usb_set_report() to ask to report tablet data. With previous addition of Bamboo Touch, BTN_TOOL_TRIPLETAP is now used for both TABLETPC2FG and BAMBOO_PT types. So reduced check to match type=TABLETPC2FG. This change shows redundant check for !TABLETPC2FG in else statement. Signed-off-by: Chris Bagwell Acked-by: Ping Cheng Signed-off-by: Dmitry Torokhov

Input: wacom - collect device quirks into single function

Collect device-specific code into a single function, and use quirks to flag specific behavior instead. Signed-off-by: Henrik Rydberg Acked-by: Ping Cheng Signed-off-by: Dmitry Torokhov

Input: wacom - parse the Bamboo device family

2010-09-05T19:58:03+00:00

The Bamboo devices have multiple interfaces which need to be setup separately. Use the HID parsing mechanism to achieve that. Signed-off-by: Ping Cheng Signed-off-by: Henrik Rydberg Signed-off-by: Dmitry Torokhov

Input: wacom - add fuzz parameters to features

2010-09-05T19:57:58+00:00

The signal-to-noise ratio varies between devices, but currently all devices are treated the same way. Add fuzz parameters to the feature struct, allowing for tailored treatment of devices. Signed-off-by: Henrik Rydberg Acked-by: Ping Cheng Signed-off-by: Dmitry Torokhov
