Hello,

When I study two driver codes that use two difference methods to wait
interrupt. One uses poll_wait in the xxx_poll function and the other uses
interrupt_sleep_on in the xxx_read function. I want to know which one will
be more real-time when driver uses one of them, that response to
application's poll()/select() or read() in the multithread condition. Thank
you.

best regards,
Gary
