Commit Message

The SPI chip selects were not properly inspected due to
a logic inversion. This made SPI GPIOs not work.

Cc: Jan Kotas <jank@cadence.com>
Reported-by: Jan Kotas <jank@cadence.com>
Tested-by: Jan Kotas <jank@cadence.com>

Fixes: f3186dd87669 ("spi: Optionally use GPIO descriptors for CS GPIOs")
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

ChangeLog v1->v3:
- New patch
- Collected Jan's Tested-by

This was rootcaused by Jan, Mark please apply this to the
SPI tree with the rest of the fixes!
