Subject: [PATCH 3/7] Input: aiptek: use descriptors of current altsetting
Date: Tue, 10 Dec 2019 12:37:33 +0100	[thread overview]
Message-ID: <20191210113737.4016-4-johan@kernel.org> (raw)
In-Reply-To: <20191210113737.4016-1-johan@kernel.org>

Make sure to always use the descriptors of the current alternate setting
to avoid future issues when accessing fields that may differ between
settings.
