Don't pass NULL to dev_info(). Either pass host->dev as the Linux
code does (and use dev_dbg rather than pr_debug), or just use printf()
(and debug()) if there's no intent to sync this change back to Linux.
It doesn't matter if host->dev doesn't exist in U-Boot, as the macro
doesn't use that parameter, but the only reason to use Linux-style
prints is to keep the code common with Linux.
understood. I prefer to use dev_xxx(host->dev, ...) to keep consistent
with kernel.
I use pr_debug because it is defined as MTDDEBUG in mtd/mtd.h, that is
exact what I want.
Since if use debug(), then when I enable debug, there are many mtd
non-related message shows up.
