From: Jiri Kosina Date: Wed, 22 Feb 2017 00:13:52 +0000 (+0100) Subject: HID: rmi: fallback to generic/multitouch if hid-rmi is not built X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2fa299a917adb2db2d486b9e4a3072865ce70a03;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git HID: rmi: fallback to generic/multitouch if hid-rmi is not built Commit 279967a65b32 ("HID: rmi: Handle all Synaptics touchpads using hid-rmi") unconditionally switches over handling of all Synaptics touchpads to hid-rmi (to make use of extended features of the HW); in case CONFIG_HID_RMI is disabled though this renders the touchpad unusable, as the HID_DEVICE(HID_BUS_ANY, HID_GROUP_RMI, HID_ANY_ID, HID_ANY_ID) match doesn't exist and generic/multitouch doesn't bind to it either (due to hid group mismatch). Fix this by switching over to hid-rmi only if it has been actually built.
