Subject: USB: gadget: Make g_hid device class conform to spec.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=33d2832ab0149a26418d360af3c444969a63fb28;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

USB: gadget: Make g_hid device class conform to spec.

HID devices should specify this in their interface descriptors, not in the
device descriptor. This fixes a "missing hardware id" bug under Windows 7 with
a VIA VL800 (3.0) controller.
