[PATCH 3/4] hw/char/xilinx_uartlite: Replace hw_error() by qemu_log_mask()
Posted by Philippe Mathieu-Daudé 5 years, 8 months ago
hw_error() calls exit(). This a bit overkill when we can log
the accesses as unimplemented or guest error.

When fuzzing the devices, we don't want the whole process to
exit. Replace some hw_error() calls by qemu_log_mask().
