From 40edea3a07ebb89e86c9bde8c94000c8f6613be7 Mon Sep 17 00:00:00 2001 From: Wolfgang Wallner Date: Wed, 16 Sep 2020 16:57:53 +0200 Subject: [PATCH] x86: acpi: Add memset to initialize SPCR table Add a missing memset to acpi_create_spcr(). The other acpi_create_xxxx() functions perform a memset on their structures, acpi_create_spcr() does not and as a result the contents of this table are partly uninitialized (and thus random after every reset).
