[PATCH 3.2 115/147] eicon: fix -Warray-bounds warning
From: Ben Hutchings
Date: Mon Nov 06 2017 - 18:51:29 EST
3.2.95-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Danny Kukawka <danny.kukawka@xxxxxxxxx>
commit e1f4c485cdb2b1d7aae172b731f6c2b403381ebb upstream.
Fix for a -Warray-bounds warning. mixer_notify_update() tries to
write to ((CAPI_MSG *) msg)->info.facility_req.structs[3] while
structs is defined as byte structs[1]. Set all 'structs' which are
part of the typdefs in the info union to 'byte structs[0]'.
v2: set all info.*.structs to byte structs[0]
