vdbg_printk() always prefixes the log messages it generates with
"FUJ02B1", which can be misleading, because it might have been called
while handling a notify for ACPI device FUJ02E3 or during module
initialization etc. Employ pr_fmt() to prefix debug messages with the
module name instead and thus avoid confusion.
