From 4a2eae2359bc79fe7d9e7463ed69ad17034fa00f Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 3 Oct 2015 19:13:12 +0100 Subject: [PATCH] PCI: mvebu: Use gpio_set_value_cansleep() We are in a context where we can sleep, and the PCIe reset gpio may be on an I2C expander. Use the cansleep() variant when setting the GPIO value.
