Subject: [PATCH 13/21] fastboot: rename usbgadget.fastboot_* variables to fastboot.*
Date: Fri, 19 Jun 2020 09:44:19 +0200	[thread overview]
Message-ID: <20200619074427.17289-14-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20200619074427.17289-1-s.hauer@pengutronix.de>

From: Daniel Glöckner <dg@emlix.com>

There is nothing USB-specific in the defined usbgadget.fastboot_*
variables. Rename them to be usable also for the UDP fastboot transport.

The usbgadget.fastboot_function variable is used to define the files and
devices accessible with the erase and flash commands. Since "function" is
a term from the USB specification and the Fastboot specification uses the
term "partition", we rename that variable to "fastboot.partitions".
