Subject: [PATCH] spi: ath79: always call chipselect function
|
||
|
|
|
||
|
|
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")
|
||
