Subject[PATCH v2 0/8] HID: Consolidate serializing ope/close in transport drivers
Date
This originally came about as report of uhid sending duplicate open and
premature close when hidraw was used alongside of input. After looking at
the drivers I think we should consolidate user tracking inside of the HID
core. While implementing this, there were a few cleanups as well.

V2:

- added greybus hid changes
- added error handling in hiddev around hid_hw_open which is __much_check

Dmitry Torokhov (8):
HID: hiddev: use hid_hw_open/close instead of usbhid_open/close
HID: hiddev: use hid_hw_power instead of usbhid_get/put_power
HID: usbhid: do not rely on hid->open when deciding to do IO
HID: serialize hid_hw_open and hid_hw_close
HID: i2c-hid: remove custom locking from i2c_hid_open/close
HID: usbhid: remove custom locking from usbhid_open/close
greybus: hid: remove custom locking from gb_hid_open/close
HID: remove no longer used hid->open field
