Gregory Nutt 72104c182c nxstyle fixes
Run all files modified by PR 766 through nxstyle and fix any resulting complaints.

NOTE:  Numerous "Mixed case identifier" errors in arch/arm/src/cxd56xx/cxd56_gnss.c were not fixed because this problem is of much larger scope than this file.

* Description:
* The inet_ntoa() function converts the Internet host address given in
* network byte order to a string in standard numbers-and-dots notation.
* The string is returned in a statically allocated buffer, which
* subsequent calls will overwrite.
