I think you misunderstood what Alan and I were saying.
If you remove the enable-bits check, then logically, all the function
does is call ata_std_prereset. Thus, your error handler only needs to
the standard function for 0x180 and 0x181, ata_std_prereset() rather
than sis_pre_reset().
Further, once your ata_bmdma_drive_eh() has been reduced entirely to
calling standard functions, you need not use sis_error_handler() at all,
because _that_ has been reduced to ata_bmdma_error_handler().
As a result, the following line
.error_handler = ata_bmdma_error_handler,
is functionally equivalent to your patch, but without custom code to
produce that effect.
