If anyone has any objections, please let me know. ------------------ From: Karl Mehltretter [ Upstream commit 12b31d1acd20b3185bb5f0748db0cf6874c8e9d1 ] __get_mtd_device() calls the master's _get_device() callback with mtd, which may be a partition. __put_mtd_device() passes the master. This breaks gluebi partitions because gluebi_get_device() uses container_of() and therefore requires the master MTD. Pass the master to _get_device(), matching _put_device().
