Message-ID: <20200730141639.b6sinzkuckxhj7ld@mobilestation> (raw)

Wou, I've confused my SOB tag here.
Linus, if no additional patchset revision is required, could you please
replace it with:
Signed-off-by: Serge Semin <Sergey.Semin@baikalelectronics.ru>
?
Alternatively I could resend the series with correct version of the tag.
