Commit 87da32356bcee42569666bef1479d0e599a556f8

Authored by Joe Perches
Committed by Linus Torvalds
1 parent 6d154db6b3
Exists in master and in 4 other branches v3.2_AM335xPSP_04.06.00.11, v3.2_NEWT335xPSP_04.06.00.11, v3.2_SBC_SMARTMEN, v3.2_SMARCT335xPSP_04.06.00.11

drivers/scsi/ch.c: don't use vprintk as macro 

It's an exported symbol of kernel/printk.c

Rename vprintk and dprintk macros to more common VPRINTK and DPRINTK
Add do { } while(0) around macros
Add level to VPRINTK so KERN_CONT can be used a couple of times.
