atl1c: Fix work event interrupt/task races
commit cb771838715b1c470bc5735bdae709b33b18e0ad upstream. The mechanism used to initiate work events from the interrupt handler has a classic read/modify/write race between the interrupt handler that sets the condition, and the worker task that reads and clears the condition. Close these races by using atomic bit fields. Cc: Jie Yang <jie.yang@atheros.com> Signed-off-by: Tim Gardner <tim.gardner@canonical.com> Signed-off-by: David S.
