From: Sergei Shtylyov Remove the following useless fragments from the driver: - the ide_dma_lostirq() and ide_dma_timeout() handlers which boil down to just printing the incoherent reset message and calling their default counterparts; - check for non-NULL drive->id in the ide_dma_check() handler -- this is assumed to be true by all other handlers (also, get rid of unnecessary nesting of the conditional statements there); - the comment before pdcnew_tune_drive() which has nothing to do with the code.
