HID: change return type of report_fixup() to const

2024-08-27T14:29:55Z

By allowing the drivers to return a "const *" they can constify their static report arrays. This makes it clear to driver authors that the HID core will not modify those reports and they can be reused for multiple devices. Furthermore security is slightly improved as those reports are protected against accidental or malicious modifications.

HID: cypress: Support Varmilo Keyboards' media hotkeys

2020-10-23T11:23:44Z

The Varmilo VA104M Keyboard (04b4:07b1, reported as Varmilo Z104M) exposes media control hotkeys as a USB HID consumer control device, but these keys do not work in the current (5.8-rc1) kernel due to the incorrect HID report descriptor. Fix the problem by modifying the internal HID report descriptor. More specifically, the keyboard report descriptor specifies the logical boundary as 572~10754 (0x023c ~ 0x2a02) while the usage boundary is specified as 0~10754 (0x00 ~ 0x2a02). This results in an incorrect interpretation of input reports, causing inputs to be ignored. By setting the Logical Minimum to zero, we align the logical boundary with the Usage ID boundary. Some notes: * There seem to be multiple variants of the VA104M keyboard. This patch specifically targets 04b4:07b1 variant. * The device works out-of-the-box on Windows platform with the generic consumer control device driver (hidserv.inf). This suggests that Windows either ignores the Logical Minimum/Logical Maximum or interprets the Usage ID assignment differently from the linux implementation; Maybe there are other devices out there that only works on Windows due to this problem?

HID: Use module_hid_driver macro

2013-01-03T09:27:31Z

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.

HID: remove Paul Walmsley's copyright from places where it shouldn't be

2012-09-05T08:46:36Z

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 Acked-by: Paul Walmsley
