Dan Carpenter fc15e3a30d rapidio/tsi721: prevent a bad dereference in tsi721_db_dpc() ... With a list_for_each() loop, if we don't find the item we are looking for in the list, then the loop exits with the iterator, which is "dbell" in this loop, pointing to invalid memory. This code uses the "found" variable to determine if we have found the doorbell we are looking for or not. However, the problem that the "found" variable needs to be set to false at the start of each iteration, otherwise after the first correct doorbell, then everything is marked as found. Reset the "found" to false at the start of the iteration and move the variable inside the loop.
