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. Cc: "James E.J. Bottomley" <[email protected]> Cc: "Martin K.
