From 7e068376c5128db2a342fa659a6dfa1488adc135 Mon Sep 17 00:00:00 2001 From: Tony Breeds Date: Wed, 23 May 2007 14:26:43 -0700 Subject: [PATCH] Fix build failure for drivers/ata/pata_scc.c The commit d4b2bab4f26345ea1803feb23ea92fbe3f6b77bc added deadline support to prereset and reset methods to libbata the pata_scc driver wasn't converted. This patch is a naive attempt to bring this driver up to scratch. Build failures are: drivers/ata/pata_scc.c: In function 'scc_pata_prereset': drivers/ata/pata_scc.c:870: error: too few arguments to function 'ata_std_prereset' drivers/ata/pata_scc.c: In function 'scc_error_handler': drivers/ata/pata_scc.c:916: warning: passing argument 2 of 'ata_bmdma_drive_eh' from incompatible pointer type drivers/ata/pata_scc.c:916: warning: passing argument 3 of 'ata_bmdma_drive_eh' from incompatible pointer type drivers/ata/pata_scc.c: In function 'scc_pata_prereset': drivers/ata/pata_scc.c:871: warning: control reaches end of non-void function On a releated note scc_bus_post_reset() is (AFACT) identical to ata_bus_post_reset(), would a patch to make ata_bus_post_reset() assesable to drivers be accepted?
