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 functionThis 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.Signed-off-by: Jeff Garzik

This is patch 16 in the series of patches that converts
Marcus Junker's w83697hf watchdog driver to Samuel Tardieau's
w83697hf/hg watchdog driver.This patch contains following changes:
- Add copyright notice for Samuel Tardieu also.This is the last patch in this series.
The original description for Samuel's driver was:
driver for the Winbond W83697HF/W83697HG watchdog timerThe Winbond SuperIO W83697HF/HG includes a watchdog that can count from
1 to 255 seconds (or minutes). This drivers allows the seconds mode to
be used. It exposes a standard /dev/watchdog interface. This chip is
currently being used on some motherboards designed by VIA.By default, the module looks for a chip at I/O port 0x2e. The chip can
be configured to be at 0x4e on some motherboards, the address can be
chosen using the wdt_io module parameter. Using 0 will try to autodetect
the address.Signed-off-by: Samuel Tardieu

This is patch 15 in the series of patches that converts
Marcus Junker's w83697hf watchdog driver to Samuel Tardieau's
w83697hf/hg watchdog driver.This patch contains following changes:
- Clean-up initialization code - part 2:
* the line reading "set second mode & disable keyboard ..."
is plain wrong, the register being manipulated (CRF4) is
the counter itself, not the control byte (CRF3) -- looks
like it has been copied from another driver.
* I think garbage is being written in CRF3 (the control word)
as the timeout value is being stored in this register (such
as 60 for 60 seconds).
* We only want to set pin 119 to WDTO# mode and leave the rest
of CR29 like it is.
* Set count mode to seconds and not minutes.Signed-off-by: Samuel Tardieu
