#1368137 — [PATCH] nvmem: Fix build error of missing devm_ioremap_resource on UM

From: Krzysztof Kozlowski <k.kozlowski@samsung.com>

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.
