scsi: Drop gdth driver

2021-01-23T02:14:07+00:00

The gdth driver refers to a SCSI parallel, PCI-only HBA RAID adapter which
was manufactured by the now-defunct ICP Vortex company, later acquired by
Adaptec and superseded by the aacraid series of controllers.  The driver
itself would require a major overhaul before any modifications can be
attempted, but seeing that it's unlikely to have any users left it should
rather be removed completely.

scsi: gdth: Make option_setup() static

2020-10-08T01:48:28+00:00

Move the two functions around the '__setup' macro which uses them to avoid
an 'unused-function' warning.

This addresses the following sparse warning:

drivers/scsi/gdth.c:3229:12: warning: symbol 'option_setup' was not
declared. Should it be static?

scsi: gdth: Only call dma_free_coherent when buf is not NULL in ioc_general

2019-03-26T02:22:44+00:00

When building with -Wsometimes-uninitialized, Clang warns:

drivers/scsi/gdth.c:3662:6: warning: variable 'paddr' is used
uninitialized whenever 'if' condition is false
[-Wsometimes-uninitialized]

Don't attempt to call dma_free_coherent when buf is NULL (meaning that
we never called dma_alloc_coherent and initialized paddr), which avoids
this warning.

scsi: gdth: use generic DMA API

2019-01-09T02:58:35+00:00

Switch from the legacy PCI DMA API to the generic DMA API.  Also switch
to dma_map_single from pci_map_page in one case where this makes the code
simpler.
