No, it does not fix that commit. The driver did sleeping allocations
even before the commit.
But wher is "here"? Can we look into not holding that lock over an
allocation if it is preferable? If not we should at least pass down
the gfp_flags so that only the caller(s) that can't sleep pass GFP_ATOMIC.
