Subject: [Patch] mtd: set master partition panic write flag
Date: Mon,  4 May 2020 19:54:02 -0400	[thread overview]
Message-ID: <20200504235403.13504-1-kdasu.kdev@gmail.com> (raw)

Check and set master panic write flag so that low level drivers
can use it to take required action to ensure oops data gets written
to assigned mtdoops device partition.
