From: Colin Ian King <colin.king@canonical.com> [ Upstream commit 17cf678a33c6196a3df4531fe5aec91384c9eeb5 ] The boolean variable pasid_mapping_needed is not initialized and there are code paths that do not assign it any value before it is is read later. Fix this by initializing pasid_mapping_needed to false.
