Subject: [PATCH] watchdog: armada_37xx: Add missing dependency on HAS_IOMEM
Git-commit: 7f6f1dfb2dcbe5d2bfa213f2df5d74c147cd5954
Patch-mainline: v5.11-rc1
References: git-fixes

The following kbuild warning is seen on a system without HAS_IOMEM.

Warning: unmet direct dependencies detected for MFD_SYSCON  Depends on [n]: HAS_IOMEM [=n]  Selected by [y]:  - ARMADA_37XX_WATCHDOG [=y] && WATCHDOG [=y] && (ARCH_MVEBU || COMPILE_TEST

This results in a subsequent compile error.

Drivers/watchdog/armada_37xx_wdt.o: in function `armada_37xx_wdt_probe':
armada_37xx_wdt.c:(.text+0xdc): undefined reference to `devm_ioremap'

Add the missing dependency.
