No. Same goes for you as every one of the forty other people a year who
try and claim their console is ttyS. If it's not an 8250 it isn't.
ttyS is the 8250, use dynamic major and minor and a different name.

You need to clear any termios features requested but not supported. In
your case that appears to be CMSPAR, as you don't seem to support
mark/space parity.
Similarly if you only support 8N1 or 7E1/7O1 you need to force the CSIZE
bits to match what you ended up setting the UART to do.

See the 8250 driver for an example: you probably need to write back the
actual rate you got.

resource_size_t for resources. Or you could just avoid the pointless
variable in the first place 8)
Other oddments - things like kasprintf() returns should be checked
