[Qemu-devel] [PATCH] ide: Turn debug messages into assertions

[Kevin Wolf]

These printfs aren't really debug messages, but clearly indicate a bug if they
ever become effective. Noone uses DEBUG_IDE, let's re-enable the check
unconditionally and make it an assertion instead of printfs in the device
emulation.
