Subject: ide: Fix status register after short PRDs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=72bcca73c7a67c8506fa737618861ad413dabf38;p=qemu.git

ide: Fix status register after short PRDs

When failing a request because the length of the regions described by
the PRDT was too short for the requested number of sectors, the IDE
emulation forgot to update the status register, so that the device would
keep the BSY flag set indefinitely.
