Brian Norris 1001ff7a4f mtd: tests: fix integer overflow issues
These multiplications are done with 32-bit arithmetic, then converted to
64-bit. We should widen the integers first to prevent overflow. This
could be a problem for large (>4GB) MTD's.

Paul Gortmaker 3ea5b037e7 mtd: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

Akinobu Mita 8a9f4aa3ac mtd: tests: incorporate error message for mtdtest_write()
All callers of mtdtest_write() print the same error message on failure.
This incorporates the error message to mtdtest_write() and removes them
from the callers.

Akinobu Mita 084db4b020 mtd: tests: introduce helper functions
This introduces the helper functions which can be used by several
mtd/tests modules.

The following three functions are used all over the test modules.

- mtdtest_erase_eraseblock()
- mtdtest_scan_for_bad_eraseblocks()
- mtdtest_erase_good_eraseblocks()

The following are wrapper functions for mtd_read() and mtd_write()
which can simplify the return value check.

- mtdtest_read()
- mtdtest_write()

All helpers are put into a single .c file and it will be linked to
every test module later.  The code will actually be copied to every
test module, but it is fine for our small test infrastructure.

[dwmw2: merge later 'return -EIO when mtdtest_read() failed' fix]
