Subject: scsi: remove DRIVER_ATTR() usage
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e14a3967723ed4a1dacd180cfc560ffc510ea2a6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

scsi: remove DRIVER_ATTR() usage

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.
