From adae28c59a6a71a971ffed713550911546df0e20 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 23 Mar 2016 11:36:53 +0100 Subject: [PATCH] mfd: syscon: Include errno.h from header The syscon header uses the ENOTSUPP error constant, but doesn't include the header that defines it. This causes a build error after the imx pinctrl driver started using syscon: include/linux/mfd/syscon.h: In function 'syscon_node_to_regmap': include/linux/mfd/syscon.h:32:18: error: 'ENOTSUPP' undeclared (first use in this function) return ERR_PTR(-ENOTSUPP); ^~~~~~~~ This adds the missing #include.
