Subject: [PATCH 0/4] tty/nozomi: general module cleanup

The nozomi module code has a fair amount of sections which could
use a bit of improvement; both style and clarity could be improved
while maintaining equivalent semantics.

Cleanup messy portions of the module code while preserving existing
behavior by:

 - Replacing constructs like `len__ > TMP_BUF_MAX ? TMP_BUF_MAX : len__`
   with `min_t(u32, len__, TMP_BUF_MAX)` and function calls like
   snprintf(tbuf, ..., "%s", ...). with strscpy(tbuf, ..., ...).
 - Rename identifiers more descriptively (where appropriate).
 - Simplify deeply nested conditionals by replacing them with shallower
   (but semantically equivalent) logic.
 - Coalesce return paths / loop conditionals.
 - Remove pointless initializations and redundant parentheses/break
   statements.
 - Correct inconsistently indented lines and extraneous whitespace.
