From: Greg Kroah-Hartman <[email protected]>
It's better to use the DRIVER_ATTR_RW() and DRIVER_ATTR_RO() macros to
explicitly show that this is a read/write or read/only sysfs file. So
convert the remaining SCSI drivers that use the old style to use the
newer macros.
Bonus is that this removes some checkpatch.pl warnings :)
This is part of a series to drop DRIVER_ATTR() from the tree entirely.

Applied to 4.14/scsi-queue. Thank you!
