Fix several errors and warnings given by checkpatch.pl: - space after opening and before closing parentheses; - opening brace following 'struct' not on the same line; - leading spaces instead of tabs; - use of C99 // comments; - macros with complex values not enclosed in parentheses; - missing space between the type and asterisk in a variable declaration; - space between asterisk and function name; - including <asm/io.h> instead of <linux/io.h> and <asm/irq.h> instead of <linux/irq.h>; - use of '__inline__' instead of 'inline'; - space between function name and opening parenthesis; - line over 80 characters. In addition to these changes, also do the following: - remove needless parentheses; - insert spaces between operator and its operands; - replace spaces after the macro name with tabs in the #define directives and after the type in the structure field declarations; - remove excess tabs after the macro name in the #define directives and in the 'extern' variable declarations; - remove excess spaces between # and define for the SSI_*_MASK macros to align with other such macros; - put '||' operator on the same line with its first operand; - properly indent multi-line function prototypes; - make the multi-line comment style consistent with the kernel style elsewhere by adding empty first line and/or adding space/asterisk on their left side; - make two-line comments that only have one line of text one-line; - convert the large multi-line comment in au1xxx_ide.h into several one-liners, replace spaces with tabs there; - fix typos/errors, capitalize acronyms, etc. in the comments; - insert missing and remove excess new lines; - update MontaVista copyright; - remove Pete Popov's and Steve Longerbeam's old email addresses...
