Subject: [PATCH 1/4] amba: reorder functions
Date: Tue, 24 Nov 2020 11:32:39 +0100	[thread overview]
Message-ID: <20201124103242.2971199-1-u.kleine-koenig@pengutronix.de> (raw)

Put helpers (here: amba_get_enable_pclk and amba_put_disable_pclk) at
the top of the file and then define callbacks directly before the
structs they are used in; in the same order.
