A quick code dig shows you should get the struct device associated
to the struct gendisk, with the disk_to_dev() macro.

In other words, something like this should work, provided 'dev' is defined
in the scope as a struct ubiblock:

  #define ubiblock_err(x) dev_err(disk_to_dev(dev->gd), x)

When the gendisk is not available, a simple pr_{} would work.
