[WATCHDOG] Fix it8712f_wdt.c wrong byte order accessing WDT_TIMEOUT
This patch corrects an error in the driver it8712f_wdt. You cannot set the 16-bit WDT_TIMEOUT access as a 16-bit outw, because the byte ordering will be wrong. So just do the high 8 bits as a separate access. Signed-off-by: Oliver Schuster <olivers137@aol.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
