[PATCH 0/5] unconfuse get_unmapped_area and point/unpoint driver methods

[Nicolas Pitre]

This is my first MTD contribution after more than 10 years.
Feels like Back to the Future!  :-)

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. Existing users won't see a difference.
