In the Linux kernel, the following vulnerability has been resolved:

i2c: pnx: Fix potential deadlock warning from del_timer_sync() call in isr

When del_timer_sync() is called in an interrupt context it throws a warning
because of potential deadlock. The timer is used only to exit from
wait_for_completion() after a timeout so replacing the call with
wait_for_completion_timeout() allows to remove the problematic timer and
its related functions altogether.
