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.
