| Subject: HID: add hid_is_usb() function to make it simpler for USB detection |
| |
| From: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
| |
| commit f83baa0cb6cfc92ebaf7f9d3a99d7e34f2e77a8a upstream. |
| |
| A number of HID drivers already call hid_is_using_ll_driver() but only |
| for the detection of if this is a USB device or not. Make this more |
| obvious by creating hid_is_usb() and calling the function that way. |
| |
| Also converts the existing hid_is_using_ll_driver() functions to use the |
| new call. |
