Tasklets have long been deprecated as being too heavy on the system by running in irq context - and this is not a performance critical path. If a higher priority process wants to run, it must wait for the tasklet to finish before doing so. c67x00_do_work() will now run in process context and have further concurrency (tasklets being serialized among themselves), but this is done holding the c67x00->lock, so it should be fine. Furthermore, this patch fixes the usage of the lock in the callback as otherwise it would need to be irq-safe.
