This series improves or implements the point and unpoint driver methods
and reimplements mtd_get_unmapped_area() in terms of those. Because
mtd->_point() provides a superset of what mtd->_get_unmapped_area() does
then there is no reason for having both. Or worse: having one but not
the other.

This is motivated by my work on XIP cramfs for both MMU and !MMU systems
where I do need the more complete point functionality. And it just looks
like the right thing to do.

This is also available on top of Linux v4.14-rc3 via git here:

  http://git.linaro.org/people/nicolas.pitre/linux mtd_point


Changes from v2:

- Minor commit log additions to patch 2 and 3.
- Added Boris Brezillon's ACK tags.
- Added Chris Brandt's Tested-by tags.

Changes from v1:

- Fix retlen computation in mtdram.c:ram_point().
- Added Richard Weinberger's REviewd-by tags.
