* All other implementations of ->speedproc return zero on success and non-zero on failure. Currently it doesn't matter for icside host driver and isn't a bug per se since: - ide_set_xfer_rate() return value is ignored by all IDE core users - icside doesn't (yet!) use ide_tune_dma() in icside_dma_check() but sooner or later we will need to fix anyway - so lets do it now. * icside_set_speed() happily accepts unsupported transfer modes which results in drive->drive_data being set to the maximum value (480) and drive->current_speed being set to the unsupported transfer mode. Fix it. v2: * The initial version of the patch was broken because it didn't take into the account (the different from usual) return values of icside_set_speed() (Noticed by Russell). v3: * Remove no longer needed initialization/checking of cycle_time (Noticed by Sergei). * No need to set drive->drive_data if DMA is not going to be used (Noticed by Sergei). * Remove incorrect setting of drive->current_speed (Noticed by Sergei). * Move ide_config_drive_speed() at the end of icside_set_speed(). v4: * If DMA mode is not found in icside_dma_check() then just return "-1" and don't call icside_set_speed() (v3 got it wrong and "1" was returned instead). v5: * Return "-1"/"0" in icside_set_speed() instead of icside_dma_check() return value (just like it was before this patch).
