mtd: Fixed checkpatch seq_printf warnings
Fixed checkpatch warnings: "WARNING: Prefer seq_puts to seq_printf"
This patch is created with reference to the ongoing lkml thread
https://lkml.org/lkml/2014/7/15/646
where Andrew Morton wrote:
"
- puts is presumably faster
- puts doesn't go rogue if you accidentally pass it a "%".
- this patch would actually make compiled object files few bytes smaller.
Perhaps because seq_printf() is a varargs function, forcing the
caller to pass args on the stack instead of in registers.
