[PATCH v2 5/8] HID: use hid_hw_wait() instead of direct call to usbhid
From: Benjamin Tissoires <hidden>
Date: 2013-02-25 10:33:03

lkml
Subsystem:
hid core layer, hid sensor hub drivers, picolcd hid driver, the rest, usb hid pid drivers (usb wheelbases, joysticks, rudders, ...), usb hid/hidbp drivers (usb keyboards, mice, remote controls, ...) · Maintainers:
Jiri Kosina, Benjamin Tissoires, Jonathan Cameron, Srinivas Pandruvada, Bruno Prémont, Linus Torvalds, Tomasz Pakuła, Oleg Makarenko
This removes most of the dependencies between hid drivers and usbhid. The patch was constructed by replacing all occurences of usbhid_wait_io() by its hid_hw_wait() counterpart. Then, drivers not requiring USB_HID anymore have their USB_HID dependency cleaned in the Kconfig file. As of today, few drivers are still requiring an explicit USB layer dependency: * ntrig (a patch is on its way) * multitouch (one patch following and another on its way) * lenovo tpkbd * roccat * sony The last three are two deeply using direct calls to the usb subsystem to be able to be cleaned right now.
