Hi,
some kind of accident seems to have happened to your patch... maybe the
missing colon after the 'From'?

The change looks good to me.

Besides the formatting of this patch, there's already a pending patch
with this same change:
https://lkml.org/lkml/2019/5/16/658
I think the original must have bounced from lkml due the encoding, but
I'll use that one since it came first, is slightly cleaner in wrapping
the line following the change, and already has Alexey's R-b. Thanks,
Alex
