[PATCH] usb: gadget: f_fs: Define pr_fmt

[Bjorn Andersson]

The majority of log entries of f_fs are generated with no indication of
their origin. Prefix these, using pr_fmt, to make the kernel log
clearer.

Why not fix the driver up to use the proper dev_*() printing functions
instead?

Or, use KBUILD_MODNAME?

I looked for that, but unless I'm completely misunderstanding the code,
there are no struct device involved to print upon. Is there some other
instance information that we'd like to include in these prints?

I can certainly use that instead of the hard coded string, if you
prefer...
