[PATCH 0/7] HID: Consolidate serializing ope/close in transport drivers

From: Dmitry Torokhov

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 shoud consolidate user tracking inside of the HID
core. While implementing this, there were a few cleanups as well.

Dmitry Torokhov (7):
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 i2c_hid_open/close
HID: remove no longer used hid->open field
