Subject: scsi_logging: return void for dev_printk() functions
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=9c4a6b1e42801343535ccab4c190019d9975cce8;p=deliverable%2Flinux.git

scsi_logging: return void for dev_printk() functions

dev_printk() is now a void function, so the related functions
scmd_printk() and sdev_prefix_printk() should be made void, too.
