Subject: [PATCH] spi: ath79: always call chipselect function
Git-commit: 19e2132174583beb90c1bd3e9c842bc6d5c944d1
Patch-mainline: v5.13-rc1
References: git-fixes

spi-bitbang has to call the chipselect function on the ath79 SPI driver
in order to communicate with the SPI slave device, as the ath79 SPI
driver has three dedicated chipselect lines but can also be used with
GPIOs for the CS lines.

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