From be1c3c1ed13f31ae8f9d5d043d96d2e56b5ee1d5 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Wed, 30 Apr 2008 23:26:28 +0400 Subject: [PATCH] [MIPS] Pb1100 code style cleanup Fix several errors and warnings given by checkpatch.pl: - space between asterisk and variable name; - use of C99 // comments; - using simple_strtol() where strict_strtol() could be used. In addition to these changes, also do the following: - properly indent the code; - remove space after the type cast's closing parenthesis; - replace numeric literals/expressions with the matching macros; - replace spaces after the macro name with tabs in the #define directives, and sometimes insert spaces there; - fix typos/errors, capitalize acronyms, etc. in the comments; - make the multi-line comment style consistent with the kernel style elsewhere by adding empty first line; - update MontaVista copyright; - remove Pete Popov's old email address...
