Subject: [PATCH] mtd: hyperbus: fix dependency and build error
From: Randy Dunlap <rdunlap@...radead.org>
lib/devres.c, which implements devm_ioremap_resource(), is only built
when CONFIG_HAS_IOMEM is set/enabled, so MTD_HYPERBUS should depend
on HAS_IOMEM. Fixes a build error and a Kconfig warning (as seen on
UML builds):
WARNING: unmet direct dependencies detected for MTD_COMPLEX_MAPPINGS
Depends on [n]: MTD [=m] && HAS_IOMEM [=n]
Selected by [m]:
- MTD_HYPERBUS [=m] && MTD [=m]
ERROR: "devm_ioremap_resource" [drivers/mtd/hyperbus/hyperbus-core.ko] undefined!
Fixes: dcc7d3446a0f ("mtd: Add support for HyperBus memory devices")
