When you're writing a changelog please mention that you fixed the
locking a little.  We normally expect checkpatch.pl fixes will not
change how the program works.

"Checkpatch.pl complained about the use of 'volatile' here.  The locking
was a bit messed up and access to the 'ch' struct should be protected
using the 'ch->ch_lock' lock.  This patch adds proper locking and
removes the bogus 'volatile'."
