Subject: [PATCH 3/4] DMA: SF_PDMA depends on HAS_IOMEM
Date: Fri, 21 May 2021 19:13:12 -0700	[thread overview]
Message-ID: <20210522021313.16405-4-rdunlap@infradead.org> (raw)
In-Reply-To: <20210522021313.16405-1-rdunlap@infradead.org>

When CONFIG_HAS_IOMEM is not set/enabled, certain iomap() family
functions [including ioremap(), devm_ioremap(), etc.] are not
available.
Drivers that use these functions should depend on HAS_IOMEM so that
they do not cause build errors.

Mends this build error:
s390-linux-ld: drivers/dma/sf-pdma/sf-pdma.o: in function `sf_pdma_probe':
sf-pdma.c:(.text+0x1668): undefined reference to `devm_ioremap_resource'

Fixes: 6973886ad58e ("dmaengine: sf-pdma: add platform DMA support for HiFive Unleashed A00")
