Subject: [PATCH 054/130] UBI: make vid_hdr non-static
commit 6bdccffe8c4268d02f71873102131fb6ed37ed9a upstream.
Remove 'static' modifier from the 'vid_hdr' local variable. I do not know
how it slipped in, but this is a bug and will break UBI if someone attaches
2 UBI volumes at the same time.
Artem: amended teh commit message, added -stable.
