Subject: [PATCH v3 1/2] HID: wacom: Add WACOM_DEVICETYPE_DIRECT for Cintiqs and similar
Date: Fri, 22 Jul 2016 16:15:02 -0700	[thread overview]
Message-ID: <20160722231503.1984-1-killertofu@gmail.com> (raw)
In-Reply-To: <20160721161200.25830-1-killertofu@gmail.com>

"Direct" input devices like Cintiqs and Tablet PCs set the INPUT_PROP_DIRECT
property to notify userspace that the sensor and screen are overlaid. This
information can also be useful elsewhere within the kernel driver, however,
so we introduce a new WACOM_DEVICETYPE_DIRECT that signals this to other
kernel code.

Changes from v2:
 * Moved setting of INPUT_PROP_DIRECT in wacom_setup_pen_input_capabilities
   and wacom_setup_touch_input_capabilities to occur before the functions
   exit if a HID_GENERIC device is being probed.

 * Changed large 'if' to 'switch' statement
