[PATCH v2] soc: fsl: qe: Avoid using gpio_to_desc()

2022-10-26 Thread Linus Walleij
We want to get rid of the old GPIO numberspace, so instead of calling gpio_to_desc() we get the gpio descriptor for the requested line from the device tree directly without passing through the GPIO numberspace, and then we get the gpiochip from the descriptor. Cc: Bartosz Golaszewski Cc: linux-g.

2022-10-26 Thread Brian King
This patch fixes an issue reported when performing a live migration when multipath is configured with a short fast fail timeout of 5 seconds and also to have no_path_retry set to fail. In this scenario, all paths would go into the devloss state while the ibmvfc driver went through discovery to log
