6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Mikko Perttunen <mperttunen@xxxxxxxxxx> [ Upstream commit 3868ff006b572cf501a3327832d36c64a9eca86a ] UBSAN reports an invalid load for bool, as the iosys_map is read later without being initialized. Zero-initialize it to avoid this.
