From 2033f6858970b98c18bed4d5ae68f43d17400abc Mon Sep 17 00:00:00 2001 From: Corey Minyard Date: Fri, 16 Aug 2019 16:13:42 -0500 Subject: [PATCH] ipmi: Free receive messages when in an oops If the driver handles a response in an oops, it was just ignoring the message. However, the IPMI watchdog timer was counting on the free happening to know when panic-time messages were complete. So free it in all cases.
