The mtd->_point method is a superset of mtd->_get_unmapped_area. Especially in the NOR flash case, the point method ensures the flash memory is in array (data) mode and that it will stay that way which is precisely what callers of mtd_get_unmapped_area() would expect. Implement mtd_get_unmapped_area() in terms of mtd->_point now that all drivers that provided a _get_unmapped_area method also have the _point method implemented.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
