Using current mainline (v2.6.35-rc3-262-g984bc96) the patch applies without problems, but when I enable it in the kernel configuration I get this: drivers/ata/sata_dwc_460ex.c:43:1: warning: "DRV_NAME" redefined In file included from drivers/ata/sata_dwc_460ex.c:38: drivers/ata/libata.h:31:1: warning: this is the location of the previous definition drivers/ata/sata_dwc_460ex.c:44:1: warning: "DRV_VERSION" redefined drivers/ata/libata.h:32:1: warning: this is the location of the previous definition drivers/ata/sata_dwc_460ex.c: In function 'sata_dwc_scr_read': drivers/ata/sata_dwc_460ex.c:777: error: 'struct ata_port' has no member named 'ioaddr' drivers/ata/sata_dwc_460ex.c: In function 'sata_dwc_scr_write': drivers/ata/sata_dwc_460ex.c:793: error: 'struct ata_port' has no member named 'ioaddr' drivers/ata/sata_dwc_460ex.c: In function 'sata_dwc_error_intr': drivers/ata/sata_dwc_460ex.c:844: error: 'struct ata_port_operations' has no member named 'sff_check_status' drivers/ata/sata_dwc_460ex.c: In function 'sata_dwc_isr': drivers/ata/sata_dwc_460ex.c:953: error: 'struct ata_port_operations' has no member named 'sff_check_status' drivers/ata/sata_dwc_460ex.c:957: error: 'struct ata_port_operations' has no member named 'sff_check_status' drivers/ata/sata_dwc_460ex.c:991: error: implicit declaration of function 'ata_sff_hsm_move' drivers/ata/sata_dwc_460ex.c:1030: error: 'struct ata_port_operations' has no member named 'sff_check_status' drivers/ata/sata_dwc_460ex.c: At top level: drivers/ata/sata_dwc_460ex.c:1213: warning: 'struct ata_ioports' declared inside parameter list drivers/ata/sata_dwc_460ex.c:1213: warning: its scope is only this definition or declaration, which is probably not what you want drivers/ata/sata_dwc_460ex.c: In function 'sata_dwc_setup_port': drivers/ata/sata_dwc_460ex.c:1215: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c:1216: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c:1218: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c:1219: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c:1221: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c:1223: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c:1224: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c:1225: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c:1227: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c:1228: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c:1229: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c:1231: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c:1232: error: dereferencing pointer to incomplete type drivers/ata/sata_dwc_460ex.c: In function 'sata_dwc_port_start': drivers/ata/sata_dwc_460ex.c:1273: error: 'struct ata_port' has no member named 'bmdma_prd' drivers/ata/sata_dwc_460ex.c:1274: error: 'struct ata_port' has no member named 'bmdma_prd_dma' drivers/ata/sata_dwc_460ex.c: In function 'sata_dwc_exec_command_by_tag': drivers/ata/sata_dwc_460ex.c:1356: warning: passing argument 1 of 'ata_get_cmd_descript' makes integer from pointer without a cast drivers/ata/sata_dwc_460ex.c:1369: error: implicit declaration of function 'ata_sff_exec_command' drivers/ata/sata_dwc_460ex.c: In function 'sata_dwc_qc_issue': drivers/ata/sata_dwc_460ex.c:1512: error: 'struct ata_port_operations' has no member named 'sff_tf_load' drivers/ata/sata_dwc_460ex.c:1516: error: implicit declaration of function 'ata_sff_qc_issue' drivers/ata/sata_dwc_460ex.c: In function 'sata_dwc_error_handler': drivers/ata/sata_dwc_460ex.c:1545: error: implicit declaration of function 'ata_sff_error_handler' drivers/ata/sata_dwc_460ex.c: At top level: drivers/ata/sata_dwc_460ex.c:1564: error: 'ata_sff_port_ops' undeclared here (not in a function) drivers/ata/sata_dwc_460ex.c:1577: error: unknown field 'bmdma_setup' specified in initializer drivers/ata/sata_dwc_460ex.c:1577: warning: initialization from incompatible pointer type drivers/ata/sata_dwc_460ex.c:1578: error: unknown field 'bmdma_start' specified in initializer drivers/ata/sata_dwc_460ex.c:1578: warning: initialization from incompatible pointer type drivers/ata/sata_dwc_460ex.c: In function 'sata_dwc_probe': drivers/ata/sata_dwc_460ex.c:1638: error: 'struct ata_port' has no member named 'ioaddr' drivers/ata/sata_dwc_460ex.c:1639: error: 'struct ata_port' has no member named 'ioaddr' drivers/ata/sata_dwc_460ex.c:1641: error: 'struct ata_port' has no member named 'ioaddr' make[2]: *** [drivers/ata/sata_dwc_460ex.o] Error 1 make[1]: *** [drivers/ata] Error 2 make: *** [drivers] Error 2 Does this require any specific kernel version?
