From: Shai Malin <smalin@xxxxxxxxxxx> [ Upstream commit e543468869e2532f5d7926e8f417782b48eca3dc ] Thanks to Kees Cook who detected the problem of memset that starting from not the first member, but sized for the whole struct. The better change will be to remove the redundant memset and to clear only the msix_cnt member.
