From: Ping Cheng Date: Wed, 23 Sep 2015 16:59:10 +0000 (-0700) Subject: HID: wacom: Cleanup unsupported device_type for BAMBOO_PT X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3b164a00a9fc;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git HID: wacom: Cleanup unsupported device_type for BAMBOO_PT Not all Bamboo support both pen and touch. Make sure we deal with pen only and touch only devices properly.
