Fix many errors and warnings given by checkpatch.pl: - space after opening and before closing parentheses; - use of C99 // comments; - leading spaces instead of tabs; - brace not on the same line with 'else' in the 'if' statement; statement; - printk() without KERN_* facility level; - using simple_strtol() where strict_strtol() could be used. - including <asm/gpio.h> instead of <linux/gpio.h>. In addition to these changes, also do the following: - insert spaces between operator and its operands; - replace tab between the function type and name with space in mtx1_pci_idsel() declaration; - remove space after the type cast's closing parenthesis; - insert missing space before closing brace in the array/structure initializers; - update MontaVista copyright; - remove Pete Popov's old email address...
