Rafał Miłecki ac9bcefa3b kernel: use V10 of mtd patchset adding support for "compatible" string
In the commit bde5e7a632 ("kernel: backport mtd implementation for
"compatible" in "partitions" subnode") patches that got accepted into
l2-mtd.git were backported to the kernels 4.9 and 4.14. Unfortunately
there was a regression report, patches were dropped and never reached
4.16.

This commit replaces these pseudo-backports with the latest version
that includes regression fix and futher changes that were requested.

Subject: [PATCH V10 3/3] mtd: ofpart: add of_match_table with
"fixed-partitions"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This allows using this parser with any flash driver that takes care of
setting of_node (using mtd_set_of_node helper) correctly. Up to now
support for "fixed-partitions" DT compatibility string was working only
with flash drivers that were specifying "ofpart" (manually or by letting
mtd use the default set of parsers).
This matches existing bindings documentation.
