From: Brendan Higgins <brendanhiggins@xxxxxxxxxx> Currently CONFIG_FSI_MASTER_ASPEED=y implicitly depends on CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get the following build error: ld: drivers/fsi/fsi-master-aspeed.o: in function `fsi_master_aspeed_probe': drivers/fsi/fsi-master-aspeed.c:436: undefined reference to `devm_ioremap_resource' Fix the build error by adding the unspecified dependency.
