Subject: HID: proper handling of MS 4k and 6k devices
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=628edcde87592a7ac6e72b555bb03ea265bcfbd2;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

HID: proper handling of MS 4k and 6k devices

This removes ugly macros IS_* to distinguish devices that
need special handling in hid-input, and establish proper
quirks for them.
