Subject: Re: [PATCH 03/10] net: Replace spi->chip_select references to
spi->chip_select[0]

But the tree is broken, isn't it? You introduce make chipselect an array
in one of the earlier patches and then change drivers one by one in
separate patches.
How about adding a inline helper function spi_chipselect(struct
spi_device *spi, unsigned int idx). Update all drivers to use that
function and then once there are no drivers left that directly reference
the chipselect field you can introduce multi-chipselect support and
update the helper function.
