console: Complete exception handling in newport_probe()

> Sorry, I do not know how to use the SmPL script.

I would like to try again to make you more familiar with applications
of the Coccinelle software.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/dev-tools/coccinelle.rst?id=b4f633221f0aeac102e463a4be46a643b2e3b819#n9

Another small example according to a script for the semantic patch language:
@display@
expression e, x;
statement is, es;
type t;
@@
*e = (t) ioremap(...)
 ... when != if( \( !e \| e == NULL \| unlikely( \( !e \| e == NULL \) ) \| WARN_ON( \( !e \| e == NULL \) ) \) ) is else es
     when != iounmap(e)
 return x;

The shown analysis approach can point 127 source files out from
the software “Linux next-20200423”. These files contain function implementations
which might need further development considerations.

You came along a few files where you noticed questionable source code.
Would you become interested to find similar places for another check?

Would you like to extend your learning experiences accordingly?

How do you think about to reduce efforts for manual code inspection?
