Igor Mammedov 71ae65e552 i2c: fix migration regression introduced by broadcast support ... QEMU fails migration with following error: qemu-system-x86_64: Missing section footer for i2c_bus qemu-system-x86_64: load of migration failed: Invalid argument when migrating from: qemu-system-x86_64-v2.6.0 -m 256M rhel72.img -M pc-i440fx-2.6 to qemu-system-x86_64-v2.7.0-rc0 -m 256M rhel72.img -M pc-i440fx-2.6 Regression is added by commit 2293c27f (i2c: implement broadcast write) Fix it by dropping 'broadcast' VMState introduced by 2293c27f and reuse broadcast 0x00 address as broadcast flag in bus->saved_address. Then if there were ongoing broadcast at migration time, set bus->saved_address to it and at i2c_slave_post_load() time check for it instead of transfering and using 'broadcast' VMState. As result of reusing existing saved_address VMState, no compat glue will be needed to keep forward/backward compatiblity. which makes fix much less intrusive.
