Subject: [PATCH AUTOSEL 4.18 05/58] spi: gpio: Fix copy-and-paste error

From: Linus Walleij <linus.walleij@...aro.org>

[ Upstream commit 1723c3155f117ee6e00f28fadf6e9eda4fc85806 ]

This fixes an embarrassing copy-and-paste error in the
errorpath of spi_gpio_request(): we were checking the wrong
struct member for error code right after retrieveing the
sck GPIO.

Fixes: 9b00bc7b901ff672 ("spi: spi-gpio: Rewrite to use GPIO descriptors")
