Date: Fri, 13 May 2016 14:12:53 +0530 From: Purna Chandra Mandal <purna.mandal@...rochip.com> To: <linux-kernel@...r.kernel.org> CC: <kbuild-all@...org>, <linux-spi@...r.kernel.org>, Purna Chandra Mandal <purna.mandal@...rochip.com>, Mark Brown <broonie@...nel.org> Subject: [PATCH] spi: pic32-sqi: Fix linker error, undefined reference to `bad_dma_ops'. Even if DMA support is disabled code using DMA mapping APIs compiles fine, but fails in linking. ------- drivers/built-in.o: In function `ring_desc_ring_free': spi-pic32-sqi.c:(.text+0x2cfbe0): undefined reference to `bad_dma_ops' spi-pic32-sqi.c:(.text+0x2cfbe4): undefined reference to `bad_dma_ops' drivers/built-in.o: In function `pic32_sqi_probe': spi-pic32-sqi.c:(.text+0x2cfe48): undefined reference to `bad_dma_ops' spi-pic32-sqi.c:(.text+0x2cfeb0): undefined reference to `bad_dma_ops' spi-pic32-sqi.c:(.text+0x2cff38): undefined reference to `bad_dma_ops' -------- Correct dependency by adding 'depends on HAS_DMA' in Kconfig.
