It's better to use the DRIVER_ATTR_RW() and DRIVER_ATTR_RO() macros to explicitly show that this is a read/write or read/only sysfs file. So convert the remaining SCSI drivers that use the old style to use the newer macros. Bonus is that this removes some checkpatch.pl warnings :) This is part of a series to drop DRIVER_ATTR() from the tree entirely. Cc: "James E.J. Bottomley" <jejb@linux.vnet.ibm.com> Cc: "Martin K.

Limit PDMA send to 512 B to avoid data corruption on DTC3181E. The corruption is always the same: one byte missing at the beginning of a 128 B block. It happens only with slow Quantum LPS 240 drive, not with faster IBM DORS-32160. It's not clear what causes this. Documentation for the DTC436 chip has not been made available. Signed-off-by:

The polling loops in pread() and pwrite() can easily become infinite loops and hang the machine. Merge the IRQ check into host buffer wait loop and add polling limit. Also place a limit on polling for 53C80 registers accessibility. [Use NCR5380_poll_politely2() for register polling. Rely on polling for gated IRQ rather than polling for phase error, like the algorithm in the 53c400 datasheet. Move DTC436 workarounds into a separate patch. Factor-out common code as wait_for_53c80_access(). Rework the residual calculations. -- F.T.] Signed-off-by:

When an IRQ arrives during PDMA transfer, pread() and pwrite() return without waiting for the 53C80 registers to be ready and this ends up messing up the chip state. This was observed with SONY CDU-55S which is slow enough to disconnect during 4096-byte reads. IRQ during PDMA is not an error so don't return -1. Instead, store the remaining byte count for use by NCR5380_dma_residual(). [Poll for the BASR_END_DMA_TRANSFER condition rather than remove the error message -- F.T.] Signed-off-by:
