File hw-block-fdc-Fix-fallback-property-on-sy.patch of Package qemu.22426
From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= <f4bug@amsat.org> Date: Wed, 7 Apr 2021 15:37:42 +0200 Subject: hw/block/fdc: Fix 'fallback' property on sysbus floppy disk controllers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Git-commit: da64789d3a16b2c5b5f1be9c75b00c2b8ae393a0 Setting the 'fallback' property corrupts the QOM instance state (FDCtrlSysBus) because it accesses an incorrect offset (it uses the offset of the FDCtrlISABus state).
