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.

The usage of strict_strtoul() is not preferred, because

mtd: introduce mtd_erase interface
This patch is part of a patch-set which changes the MTD interface
from 'mtd->func()' form to 'mtd_func()' form. We need this because
we want to add common code to to all drivers in the mtd core level,
which is impossible with the current interface when MTD clients
call driver functions like 'read()' or 'write()' directly.
At this point we just introduce a new inline wrapper function, but
later some of them are expected to gain more code. E.g., the input
parameters check should be moved to the wrappers rather than be
duplicated at many drivers.
This particular patch introduced the 'mtd_erase()' interface. The
following patches add all the other interfaces one by one.

affected operations on in-band page data as well. To clarify these

As Artem Bityutskiy suggested: this option is controversial, as we

it as a config parameter. So, better kill it and let the real mtdswap
