[Qemu-devel] [PATCH for-3.1 2/2] hw/block/onenand: use qemu_log_mask() for reporting

[Peter Maydell]

Update the onenand device to use qemu_log_mask() for reporting
guest errors and unimplemented features, rather than plain
fprintf() and hw_error().

(We leave the hw_error() in onenand_reset(), as that is
triggered by a failure to read the underlying block device
for the bootRAM, not by guest action.)
