Subject: [PATCH 5.12 007/178] dmaengine: SF_PDMA depends on HAS_IOMEM
Date: Mon, 21 Jun 2021 18:13:41 +0200	[thread overview]
Message-ID: <20210621154921.712666505@linuxfoundation.org> (raw)
In-Reply-To: <20210621154921.212599475@linuxfoundation.org>

From: Randy Dunlap <rdunlap@infradead.org>

[ Upstream commit 8e2e4f3c58528c6040b5762b666734f8cceba568 ]

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'
