MTD fixes for OF node refcounting

[PATCH 0/2] MTD fixes for OF node refcounting

Posted by Cosmin Tanislav 3 weeks, 6 days ago

This series fixes an issue observed while repeatedly binding / unbinding
the SPI controller driver to which a SPI NOR flash memory is attached,
caused by commit 7cce81df7d26 ("mtd: parsers: ofpart: fix OF node
refcount leak in parse_fixed_partitions()"). See patch 2 for more
details.

Patch 1 is the fix for another theorethical issue I have noticed while
debugging the main issue.

Cosmin Tanislav (2):
  mtd: parsers: ofpart: call of_node_put() only in ofpart_fail path
  mtd: parsers: ofpart: call of_node_get() for dedicated subpartitions

Patche(s) should be available on mtd/linux.git and will be
part of the next PR (provided that no robot complains by then).

Kind regards,
