Subject[ 17/78] mtd: docg3: initialize writebufsize
3.3-stable review patch.  If anyone has any objections, please let me know.


From: Artem Bityutskiy <>

commit 82c4c58d6f1a78e8de875272a19ab9220b8066aa upstream.

The writebufsize concept was introduce by commit
"0e4ca7e mtd: add writebufsize field to mtd_info struct" and it represents
the maximum amount of data the device writes to the media at a time. This is
an important parameter for UBIFS which is used during recovery and which
basically defines how big a corruption caused by a power cut can be.

Set it to be equivalent to mtd->writesize because this is the maximum amount
of data the driver writes at a time.
