[PATCH v2 0/8] HID: Consolidate serializing ope/close in transport drivers

Show all headers | View raw

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
