Subject: [PATCH net-next 20/22] can/esd_usb: Rename all terms USB2 to USB
Date: Sat, 25 Jun 2022 14:03:33 +0200	[thread overview]
Message-ID: <20220625120335.324697-21-mkl@pengutronix.de> (raw)
In-Reply-To: <20220625120335.324697-1-mkl@pengutronix.de>

From: Frank Jungclaus <frank.jungclaus@esd.eu>

Each occurrence of the term "usb2" within variables, function names,
comments, etc. is changed to "usb" where it is shared for all
esd CAN/USB devices.
