Subject: [PATCH v2] eicon: fix -Warray-bounds warning
Date: Thu,  2 Feb 2012 14:20:28 +0100	[thread overview]
Message-ID: <1328188830-28133-1-git-send-email-danny.kukawka@bisect.de> (raw)

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]
