From 17fa81aa702ec118f2b835715897041675b06336 Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Thu, 17 Dec 2020 14:29:14 -0800 Subject: spi: spi-geni-qcom: Print an error when we timeout setting the CS If we're using geni to manage the chip select line (don't do it--use a GPIO!) and we happen to get a timeout waiting for the chip select command to be completed, no errors are printed even though things might not be in the best shape.
