2012-09-19HID: picoLCD: drop version check during probeBruno Prémont1-18/+0
Commit 4ea5454203d991ec85264f64f89ca8855fce69b0 [HID: Fix race condition between driver core and ll-driver] introduced new locking around probe/remove functions that prevents any report/reply from hardware to reach driver until it returned from probe. As such, the ask-reply way to checking picoLCD firmware version during probe is bound to timeout and let probe fail. Drop the check to let driver successfully probe again (until locking issues are resolved allowing to reinstate the check).

Adding processing for HID Sensor usage table as defined by HID 1.12, Request #: HUTRR39, dated 05 May, 2011. This driver uses HID driver framework to register, send and receive events. This uses MFD framework, so that actual processing for a specific usage id can be done in a different driver. For example an accelerometer driver can be a separate driver and use the interface provided by this driver to register for events.

2012-09-05HID: picoLCD: rework hid-fbdev interactionBruno Prémont2-109/+126
Split out all FB related data out of struct picolcd_data into a struct picolcd_fb_data that is allocated with fb_info. This way fb_info may cleanly outlive struct picolcd_data for as long as needed for its last user to drop his reference. Access to struct picolcd_data is now protected with struct picolcd_fb_data's lock and tile update reports are only generated while picolcd_fbdata->picolcd is not NULL and is not marked as failed (which indicates unplug in progress).

2012-09-05HID: remove Paul Walmsley's copyright from places where it shouldn't beJiri Kosina17-17/+0
Paul Walmsley has implemented dynamic quirk handling back in 2007 through commits: 2eb5dc30eb ("USB HID: encapsulate quirk handling into hid-quirks.c") 8222fbe67c ("USB HID: clarify static quirk handling as squirks") 8cef908235 ("USB HID: add support for dynamically-created quirks") 876b9276b9 ("USB HID: add 'quirks' module parameter") and as such, his copyright rightly belongs to drivers/hid/usbhid/hid-quirks.c file. However when generic HID code has been converted to bus and individual quirks separated out to individual drivers on the bus, the copyright has been blindly transfered into all the tiny drivers, which actually don't contain any of Pauls' copyrighted code. Remove the copyright from those sub-drivers. Signed-off-by: Jiri Kosina <[email protected]> Acked-by: Paul Walmsley <[email protected]>
2012-09-03HID: Remove "default m" from HID_LOGITECH_DJJosh Triplett1-1/+0
HID_LOGITECH_DJ uses "default m", which enables it in default kernel builds. Since this module just enables extra, non-critical functionality for one particular piece of hardware (specifically, differentiating multiple wireless keyboards and mice as separate input devices rather than treating them as one device), and the hardware works just fine with the default USB HID support, drop the "default m".
