Unfortunately (built with W=1):

drivers/watchdog/st_wdt.c: In function 'st_wdog_load_timer':
drivers/watchdog/st_wdt.c:114:14: warning: comparison between signed and
unsigned integer expressions [-Wsign-compare]
drivers/watchdog/st_wdt.c: In function 'st_wdog_remove':
drivers/watchdog/st_wdt.c:273:24: error: 'clk' undeclared (first use in this
function)

and checkpatch complains a bit: 

WARNING: please, no space before tabs
#303: FILE: drivers/watchdog/st_wdt.c:236:
+^Ist_wdog->dev ^I^I= &pdev->dev;$

WARNING: please, no space before tabs
