It is generally a bad idea. It makes back porting fixing harder if the
file changes name.

And what does bt1 stand for?

How about nxp-c45-tja11xx.c. It is not ideal, but it does at least
give an indication of what devices it does cover, even if there is a
big overlap with nxp-tja11xx.c, in terms of pattern matching. And if
you do decide to have a major change of registers, your can call the
device tja1201 and have a new driver nxp-c45-tja12xx.
