[PATCH v2] nvmem: Fix build error of missing devm_ioremap_resource on UM

From: Krzysztof Kozlowski
Date: Thu Mar 03 2016 - 20:03:14 EST


The devres.o gets linked if HAS_IOMEM is present so on ARCH=um
allyesconfig (COMPILE_TEST) failed on many files with:

drivers/built-in.o: In function `mtk_thermal_probe':
mtk_thermal.c:(.text+0x394618): undefined reference to `devm_ioremap_resource'

The users of devm_ioremap_resource() which are compile-testable should
depend on HAS_IOMEM.
