Subject: HID: proper handling of MS 4k and 6k devices
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=628edcde87592a7ac6e72b555bb03ea265bcfbd2;p=openwrt%2Fstaging%2Fblogic.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.
