Subject: [PATCH] spi: ath79: always call chipselect function
From: David Bauer <[email-masked]>
Date: Wed, 17 Feb 2021 02:44:55 +0100

api-bitbang has to call the chipselect function on the ath79 SPI driver
in order to communicate with the SPI slave device.

Fixes commit 4a07b8bcd503 ("spi: bitbang: Make chipselect callback optional")
