intel-mid_wdt: Error code is just an integer
Error code when printed is more readable if it's represented as plain decimal integer. Otherwise user will see something like intel_mid_wdt: Error stopping watchdog: 0xffffffed which is not quite understandable ("Should I interpret it as a bitfield?"). Make it clear to use plaint integer specifier. While here, move struct device *dev local variable definition to the top of functions.
