From: Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx> [ Upstream commit fa4e7fc1386078edcfddd8848cb0374f4af74fe7 ] xsdfec_poll() is defined as returning 'unsigned int' but the .poll method is declared as returning '__poll_t', a bitwise type. Fix this by using the proper return type and using the EPOLL constants instead of the POLL ones, as required for __poll_t.
