2013-01-31HID: i2c-hid: fix i2c_hid_output_raw_reportBenjamin Tissoires
i2c_hid_output_raw_report is used by hidraw to forward set_report requests. The current implementation of i2c_hid_set_report needs to take the report_id as an argument. The report_id is stored in the first byte of the buffer in argument of i2c_hid_output_raw_report. Not removing the report_id from the given buffer adds this byte 2 times in the command, leading to a non working command.

2013-01-03Drivers: misc: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

Patch to add the Formosa Industrial Computing, Inc. Infrared Receiver [IR605A/Q] to hid-ids.h and hid-quirks.c. This IR receiver causes about a 10 second timeout when the usbhid driver attempts to initialze the device. Adding this device to the quirks list with HID_QUIRK_NO_INIT_REPORTS removes the delay.

2012-12-07HID: hidp: fallback to input session properly if hid is blacklistedLamarque V. Souza
This patch against kernel 3.7.0-rc8 fixes a kernel oops when turning on the bluetooth mouse with id 0458:0058 [1]. The mouse in question supports both input and hid sessions, however it is blacklisted in drivers/hid/hid-core.c so the input session is one that should be used. Long ago (around kernel 3.0.0) some changes in the bluetooth subsystem made the kernel do not fallback to input session when hid session is not supported or blacklisted. This patch restore that behaviour by making the kernel try the input session if hid_add_device returns ENODEV. The patch exports hid_ignore() from hid-core.c so that it can be used in the bluetooth subsystem. [1] https://bugzilla.kernel.org/show_bug.cgi?id=39882 Signed-off-by: Lamarque V.
