Hi Andrew

My compile just failed with 

drivers/scsi/gdth.c: In function ‘gdth_search_dev’:
drivers/scsi/gdth.c:646: warning: ‘pci_find_device’ is deprecated
(declared at include/linux/pci.h:482)
drivers/scsi/gdth.c: In function ‘gdth_init_isa’:
drivers/scsi/gdth.c:857: error: ‘gdth_irq_tab’ undeclared (first use in
this function)

only once
drivers/scsi/gdth.c:857: error: for each function it appears in.)
drivers/scsi/gdth.c: In function ‘gdth_copy_internal_data’:

make[1]: *** [drivers/scsi] Error 2
make: *** [drivers] Error 2
[dhaval@...dor linux-2.6.23]$

Looking into the code I notice that gdth_irq_tab is not declared with
CONFIG_ISA=y and !CONFIG_EISA.

The values seem to be same in 2.6.23 (I am not sure why it has been put
with #ifdefs in -mm) so I have just modified the #ifdef to take care of
CONFIG_ISA as well.

(Compile tested only)

Thanks,
