[PATCH v0 2/7] bluetooth: Fix minor style issues

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Mikel Astiz <mikel.astiz@xxxxxxxxxxxx>

Trivially fix some style issues affecting line wrap (128 chars max with
the exception of multi-line comments, which are limited to 80),
indentation and unnecessary parentheses.
