In old days, the MTD subsystem in Linux had debug facility like DEBUG(MTD_DEBUG_LEVEL1, ...).
They were all replaced with pr_debug() until Linux 3.2. See Linux commit 289c05222172 ("mtd: replace DEBUG() with pr_debug()").
U-Boot still uses similar macros. Covert all of them for easier sync.
Done with the help of Coccinelle.
The semantic patch I used is as follows:
// <smpl> @@ expression e1, e2; @@ -MTDDEBUG(e1, e2) +pr_debug(e2) @@ expression e1, e2; @@ -MTDDEBUG(e1, e2, +pr_debug(e2, ...) // </smpl>
