Or maybe combine these in the ubi_<level> calls passing
NULL when there is no struct ubi_device *
void ubi_err(const struct ubi_device *ubi, fmt. ...)
{
struct va_format vaf;
va_list args;
va_start(args, fmt);
vaf.fmt = fmt;
vaf.va = &args;
if (ubi && ubi->gd)
dev_err(disk_to_dev(dev->gd), "UBI-%d error: %pF %pV",
ubi->ubi_num, __builtin_return_address(0), &vaf);
else if (ubi)
printk(KERN_ERR "UBI-%d error: %pf: %pV",

else
printk(KERN_ERR "UBI: error: %pf: %pV",
