Subject: [PATCH] scsi: pm8001: clean up structurally dead code when PM8001_USE_MSIX is defined (part2)

From: Colin Ian King <[email protected]>

When macro PM8001_USE_MSIX is defined there is redundant dead code
call to pm8001_cr32. Clean this up for the defined PM8001_USE_MSIX and
undefined PM8001_USE_MSIX cases.

Also rename the functions pm8001_chip_is_our_interupt,
pm80xx_chip_is_our_interupt and function pointer is_our_interrupt
to fix spelling mistakes.

It would be better if you could split this into two patch, one for dead
code and other for renaming.

Otherwise change looks good.

Once you fix above you could include .
