Hello Yury,

There was a race during applying this patch. So currently linux-next has 2 versions of it.

The first one is 1a339a14b1f2c7a0dfdd6db79eee1e55d3cec357, which is original.
The second one is 7ede8665f27cde7da69e8b2fbeaa1ed0664879c5, updated by Will Deacon and
applied to the mainline.

I'm sorry for that. The first one should be definitely dropped.

Best regards,
Alexander
