This isn't for applying so much as it is for showing people where I am
with this driver. As with the sym2 driver, I commit each piece to the
parisc-linux CVS tree (since parisc is currently the only user of this
driver, it makes even more sense to do development there). This patch
contains workarounds for a bug that is fixed in scsi-misc-2.6, so I'm
waiting for that to be merged with Linus, then I'll submit this patch
minus those workarounds.
- record an sdev instead of the starget in the target struct
- set the sdev (should be starget) in slave_alloc instead of
slave_configure to avoid problems with drives sending negotiation
messages before we try to configure them.
(actually, testing the same workaround in the sym2 driver revealed
a problem with multilun devices that I've fixed in sym2 and haven't
here. This problem goes away with the scsi-misc-2.6 bugfix, so I'm
not inclined to fix it.)
- Implement ->get_signalling.
- Pass the scsi_cmnd to ncr_get_ccb() instead of the target & lun numbers
- All ncr_show_msg() callers changed to use ncr_print_msg()
- Combine ncr_show_msg() into ncr_print_msg()
- Move ncr_print_msg() to near the top of the file and eliminate prototype
- Change PRINT_ADDR() to take a fmt string
- Make PRINT_ADDR use dev_info()
- Eliminate PRINT_LUN -- all callers can use PRINT_ADDR or dev_info
- Replace PRINT_TARGET() with a direct call to dev_info()
- Whitespace cleanups
- Get rid of superfluous ; after } of if/switch statements
- Use IDENTIFY() instead of M_IDENTIFY | ...
- Convert to use spi_display_xfer_agreement()

"Next the statesmen will invent cheap lies, putting the blame upon
the nation that is attacked, and every man will be glad of those
conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince
himself that the war is just, and will thank God for the better sleep
he enjoys after this process of grotesque self-deception." -- Mark Twain
