Subject: [PATCH 4/4] DMA: XILINX_ZYNQMP_DPDMA depends on HAS_IOMEM
Date: Fri, 21 May 2021 19:13:13 -0700 [thread overview]
Message-ID: <20210522021313.16405-5-rdunlap@infradead.org> (raw)
In-Reply-To: <20210522021313.16405-1-rdunlap@infradead.org>
When CONFIG_HAS_IOMEM is not set/enabled, most 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.
Cures this build error:
s390-linux-ld: drivers/dma/xilinx/xilinx_dpdma.o: in function `xilinx_dpdma_probe':
xilinx_dpdma.c:(.text+0x336a): undefined reference to `devm_platform_ioremap_resource'
Fixes: 7cbb0c63de3fc ("dmaengine: xilinx: dpdma: Add the Xilinx DisplayPort DMA engine driver")
