[ Upstream commit5e6ddadf76] Building ufshcd-pltfrm.c on arch/s390/ has a linker error since S390 does not support IOMEM, so add a dependency on HAS_IOMEM. s390-linux-ld: drivers/scsi/ufs/ufshcd-pltfrm.o: in function `ufshcd_pltfrm_init': ufshcd-pltfrm.c:(.text+0x38e): undefined reference to `devm_platform_ioremap_resource' where that devm_ function is inside an #ifdef CONFIG_HAS_IOMEM/#endif block.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
