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 drivers/hid/hid-core.c | 89 +++++++++++++++++++++++++ drivers/hid/i2c-hid/i2c-hid.c | 32 +++------ drivers/hid/usbhid/hid-core.c | 150 ++++++++++++++++++++---------------------- drivers/hid/usbhid/hiddev.c | 12 ++-- drivers/hid/usbhid/usbhid.h | 15 +++-- include/linux/hid.h | 73 +++----------------- 6 files changed, 194 insertions(+), 177 deletions(-) Thanks. -- Dmitry
