Subject: mtd: core: fix nvmem error reporting
From: Michael Walle <michael@xxxxxxxx>
commit 8bd1d24e6ca3c599dd455b0e1b22f77bab8290eb upstream.
The master MTD will only have an associated device if
CONFIG_MTD_PARTITIONED_MASTER is set, thus we cannot use dev_err() on
mtd->dev. Instead use the parent device which is the physical flash
memory.
