| | | | | | | | | | | | | | | | | | All custom ->dma_timeout implementations call the generic one thus it is possible to have only an optional method for resetting DMA engine instead: * Add ->dma_clear method and convert hpt366, pdc202xx_old and sl82c105 host drivers to use it. * Always use ide_dma_timeout() in ide_dma_timeout_retry() and remove ->dma_timeout method. * Make ide_dma_timeout() static.

* platform driver: fix incorrect use of 'platform_bus_type' with 'struct ↵Ming Lei2009-03-241-18/+18
| | | | | | | | | | | | | | | | | | | | | | device_driver' This patch fixes the bug reported in http://bugzilla.kernel.org/show_bug.cgi?id=11681. "Lots of device drivers register a 'struct device_driver' with the '.bus' member set to '&platform_bus_type'. This is wrong, since the platform_bus functions expect the 'struct device_driver' to be wrapped up in a 'struct platform_driver' which provides some additional callbacks (like suspend_late, resume_early). The effect may be that platform_suspend_late() uses bogus data outside the device_driver struct as a pointer pointer to the device driver's suspend_late() function or other hard to reproduce failures."(Lothar Wassmann) Signed-off-by: Ming Lei <tom.leiming@gmail.com> Acked-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* ide: move read_sff_dma_status() method to 'struct ide_dma_ops'Sergei Shtylyov2009-01-061-1/+0
| | | | | | | | | | | | Move apparently misplaced read_sff_dma_status() method from 'struct ide_tp_ops' to 'struct ide_dma_ops', renaming it to dma_sff_read_status() and making only required for SFF-8038i compatible IDE controller drivers (greatly cutting down the number of initializers) as its only user (outside ide-dma-sff.c and such drivers) appears to be ide_pci_check_simplex() which is only called for such controllers...
