[WATCHDOG] watchdog/iTCO_wdt: fix bug related to gcc uninit warning
gcc emits the following warning: drivers/char/watchdog/iTCO_wdt.c: In function ‘iTCO_wdt_ioctl’: drivers/char/watchdog/iTCO_wdt.c:429: warning: ‘time_left’ may be used uninitialized in this function This indicates a condition near enough to a bug, to want to fix. iTCO_wdt_get_timeleft() stores a value in 'time_left' iff iTCO_version==(1 or 2). This driver only supports versions 1 or 2, so this is ok. However, since (a) the return value of iTCO_wdt_get_timeleft() is handled anyway, (b) it fixes the warning, and (c) it future-proofs the driver, we go ahead and add the obvious return value.
