Subject: [PATCH 12/12] imx-usb-loader: drop some unnecessary casting
Date: Thu, 14 Jul 2022 09:27:22 +0200	[thread overview]
Message-ID: <20220714072722.2863571-13-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20220714072722.2863571-1-s.hauer@pengutronix.de>

Change the buffer pointer in transfer() to type void * to drop some
unnecessary type casting from the callers.
