The driver uses the string "slcan" to populate
tty_ldisc_ops::name. KBUILD_MODNAME also evaluates to "slcan". Use
KBUILD_MODNAME to get rid on the hardcoded string names.
Similarly, the pr_info() and pr_err() hardcoded the "slcan"
prefix. Define pr_fmt so that the "slcan" prefix gets automatically
added.
can: ems_ubs: use KBUILD_MODNAME instead of hard coded name
The driver uses the string "ems_usb" to populate usb_driver::name and
can_bittiming_const::name. KBUILD_MODNAME also evaluates to
"ems_ubs". Use KBUILD_MODNAME and get rid on the hardcoded string
names.

@Dario, because you are also doing a lot of changes on slcan, our
patches might conflict. Do not hesitate to take this one and add it to
your series to simplify the merge.
