Subject: [PATCH v4 11/11] HID: hexLIN: Implement ability to update lin mode
Date: Thu,  9 May 2024 19:17:36 +0200	[thread overview]
Message-ID: <20240509171736.2048414-12-christoph.fritz@hexdev.de> (raw)
In-Reply-To: <20240509171736.2048414-1-christoph.fritz@hexdev.de>

Enhance the hexLIN driver by implementing the newly introduced
update_lin_mode() callback.  So that either commander or responder mode
can be configured on this hardware.
