Subject: [PATCH] mtd: mtdoops: Fix kmsgdump parameter renaming.

When the kmsg_dumper callback parameter changed, the reason variable
in mtdoops_do_dump() was not updated accordingly.
This breaks the build with mtdoops.

Fixes: e1a261ba599e ("printk: Add a short description string to kmsg_dump()")
Reported-by: Knop Ryszard <ryszard.knop@...el.com>
Signed-off-by: Jocelyn Falempe <jfalempe@...hat.com>

The offended commit is in the drm-misc tree, because it was needed
by drm_panic. So I will push the fix there too.
