[PATCH 5.0 081/101] gpio: of: Check for "spi-cs-high" in child instead of parent node

From: Greg Kroah-Hartman
Date: Thu May 02 2019 - 11:32:26 EST


[ Upstream commit 7ce40277bf848391705011ba37eac2e377cbd9e6 ]

"spi-cs-high" is going to be specified in child node of an SPI
controller's representing attached SPI device, so change the code to
look for it there, instead of checking parent node.
