[Qemu-devel] [PATCH] hw/pc.c: Fix use-while-uninitialized of fd_type[]

[Peter Maydell]

Fix a use-while-uninitialized of the fd_type[] array (introduced
in commit 34d4260e1, noticed by Coverity). This is more theoretical
than practical, since it's quite hard to get here with floppy==NULL
(the qdev_try_create() of the isa-fdc device has to fail).
