FWIW I am not entrely happy with the whole send-and_wait implementation -
it looks like it is not being called concurrently so we don't need mutex
there... I'd do something like:
send_nand_wait() {
set_bit(WAITING_RESPONSE, data->state);
prepare message
send message
wait_for_event_interruptible_timeout(&data->wait,
!test_bit(WAITING_RESPONSE, data->state));
if (!test_bit()) {
process
return 0;
}
return -ETIME;
}
irq(...) {
else if (test_bit(WAITING_RESPONSE, data->state)) {
copy response...
clear_bit(WAITING_RESPONSE, data->state);
wake_up(&data->wait);
}
}
and not bother with kmallocing pending structure, but it should not
stop from merging driver.
