greybus: loopback: make loopback code thread safe
Current code allows a sysfs callback and a kernel worker thread to write all over and act upon data that could be in the process of being updated by the other. This patch adds a reasonably coarse mutex to enscure sync between the two. Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@google.com>
