Subject: Bluetooth: hidp: Add support for NO_INIT_REPORTS quirk
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=142c69c6eaab26587264881bb71546e30aafdcee;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

Bluetooth: hidp: Add support for NO_INIT_REPORTS quirk

During setup the host initializes all HID reports. Some devices do not
support this. If this quirk is set, we skip the initialization.
See also usbhid_init_reports() for this quirk.
