Fix several errors and warnings given by checkpatch.pl: - macros with complex values not enclosed in parentheses; - leading spaces instead of tabs; - printk() without KERN_* facility level; - using simple_strtol() where strict_strtol() could be used; - line over 80 characters. In addition to these changes, also do the following: - initialize variable instead of assigning value later where it makes sense; - insert spaces between operator and its operands, also remove excess spaces there; - remove unneeded numeric literal type casts; - remove needless parentheses; - remove space after the type cast's closing parenthesis; - insert missing space before closing brace in the array initializers; - replace spaces after the macro name with tabs in the #define directives; - remove excess tabs after the macro name in the #define directives; - 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/last line; - update MontaVista copyright; - remove Pete Popov's old email address...
