Subject: HID: avoid sparse warning in HID_COMPAT_LOAD_DRIVER
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=725cf0f47dbb02e0482f081828cff73f55479b79;p=mv-sheeva.git

HID: avoid sparse warning in HID_COMPAT_LOAD_DRIVER

Impact: include a prototype for the exported function in the macro

Fix about 20 of this warnings:

  drivers/hid/hid-a4tech.c:162:1: warning: symbol 'hid_compat_a4tech' was not declared. Should it be static?
