in the original submission a...@kernel.org was not included, but it looks like
the patch should go through arm-soc.
We have two tags
Acked-by: Will Deacon <will.dea...@arm.com>
Tested-by: Heiko Stuebner <he...@sntech.de>
Can you find the original patch somehow or should it be resend to include
a...@kernel.org ?
Thanks
Heiko
