Subject: [PATCH 5/7] HID: uclogic: Access pen/frame params directly in raw_event handling
Date: Thu, 10 Feb 2022 20:04:35 +0100	[thread overview]
Message-ID: <20220210190437.50152-6-jose.exposito89@gmail.com> (raw)
In-Reply-To: <20220210190437.50152-1-jose.exposito89@gmail.com>

From: Nikolai Kondrashov <spbnick@gmail.com>

Simplify the raw event handling code by accessing the
uclogic_params_pen/uclogic_params_frame structs directly.
