Subject: [PATCH] spi/ath79: remove superfluous chip select code
|
|
|
|
commit f1e8fc9898fd8ca78b7438d3c2e60028d3ae2a34 upstream.
|
|
|
|
The spi_bitbang driver calls the chipselect function
|
|
of the driver from spi_bitbang_setup in order to
|
|
deselect the given SPI chip, so we don't have to
|
|
initialize the CS line here.
