From 655fc39bf40331e13503bed85c9ed0278bc35575 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 9 Jul 2014 21:04:00 +0200 Subject: firewire: IEEE 1394 (FireWire) support should depend on HAS_DMA Commit b3d681a4fc108f9653bbb44e4f4e72db2b8a5734 ("firewire: Use COMPILE_TEST for build testing") added COMPILE_TEST as an alternative dependency for the purpose of build testing the firewire core. However, this bypasses all other implicit dependencies assumed by PCI, like HAS_DMA. If NO_DMA=y: drivers/built-in.o: In function `fw_iso_buffer_destroy': (.text+0x36a096): undefined reference to `dma_unmap_page' drivers/built-in.o: In function `fw_iso_buffer_map_dma': (.text+0x36a164): undefined reference to `dma_map_page' drivers/built-in.o: In function `fw_iso_buffer_map_dma': (.text+0x36a172): undefined reference to `dma_mapping_error' drivers/built-in.o: In function `sbp2_send_management_orb': sbp2.c:(.text+0x36c6b4): undefined reference to `dma_map_single' sbp2.c:(.text+0x36c6c8): undefined reference to `dma_mapping_error' sbp2.c:(.text+0x36c772): undefined reference to `dma_map_single' sbp2.c:(.text+0x36c786): undefined reference to `dma_mapping_error' sbp2.c:(.text+0x36c854): undefined reference to `dma_unmap_single' sbp2.c:(.text+0x36c872): undefined reference to `dma_unmap_single' drivers/built-in.o: In function `sbp2_map_scatterlist': sbp2.c:(.text+0x36ccbc): undefined reference to `scsi_dma_map' sbp2.c:(.text+0x36cd36): undefined reference to `dma_map_single' sbp2.c:(.text+0x36cd4e): undefined reference to `dma_mapping_error' sbp2.c:(.text+0x36cd84): undefined reference to `scsi_dma_unmap' drivers/built-in.o: In function `sbp2_unmap_scatterlist': sbp2.c:(.text+0x36cda6): undefined reference to `scsi_dma_unmap' sbp2.c:(.text+0x36cdc6): undefined reference to `dma_unmap_single' drivers/built-in.o: In function `complete_command_orb': sbp2.c:(.text+0x36d6ac): undefined reference to `dma_unmap_single' drivers/built-in.o: In function `sbp2_scsi_queuecommand': sbp2.c:(.text+0x36d8e0): undefined reference to `dma_map_single' sbp2.c:(.text+0x36d8f6): undefined reference to `dma_mapping_error' Add an explicit dependency on HAS_DMA to fix this.
