From 3085a4a459c91b7e8647d25b38b975c334e78c8c Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 3 Oct 2016 09:46:58 +0200 Subject: [PATCH] gpio: make memory-mapped drivers depend on HAS_IOMEM This one is pretty obvious: on UM Linux compilation of things like allmodconfig and allyesconfig will fail due to the absence of IO memory. Simply make these drivers depend on HAS_IOMEM, it has been implicitly assumed all the time, so just make it explicit. The generic MMIO library also assumes that IOMEM is present so make also this depend on HAS_IOMEM.
