From 8e6a5c833333e14a5023a5dcabb64b7d9e046bc6 Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck Date: Wed, 20 Nov 2019 01:07:41 +0100 Subject: [PATCH] ipmi: fix ipmb_poll()'s return type ipmb_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.
