Hi,
Most of drivers use sg helpers to operate sgl, however there is
still a few drivers which operate sgl directly, this way can't
work in case of chained sgl.
So convert them to use sg helper.
There are two types of scsi SGL uses:
1) operate on scsi_sglist(scmd) directly, then one local variable of
'struct scatterlist *' is involved, so the following coccinelle semantic
patch is developed for finding this type of direct sgl uses:
https://marc.info/?l=linux-scsi&m=156031374809852&w=2
2) scsi_sglist(scmd) is stored to cmd->SCp.buffer and the SGL is used
via cmd->SCp.buffer. Simple 'grep SCp.buffer' is used for finding SGL
direct uses, fortunately only the following drivers uses SCp.buffer to
store SGL:
NCR5380, aha152x, arm/, imm, pcmcia, ppa and wd33c93
And arm/ is already ready to handle chained SGL.
The 1st 9 patches are for handling type #1, and the other 6 patches
for handling type #2.
V2:
- use coccinelle semantic patch for finding direct sgl uses from
scsi command(9 drivers found)
- run 'git grep -E "SCp.buffer"' to find direct sgl uses
from SCp.buffer(6 drivers are found)
