Is there any circumstance in which it is ok to call release_resource on 
the result of calling request(_mem)_region?  One issue is that 
release_resource doesn't free its argument, but then what if the call to 
release_resource is followed by a call to kfree?

Example:
drivers/watchdog/s3c2410_wdt.c, in the function s3c2410wdt_probe

thanks,
julia

Best to ask on lkml.  Greg is the maintainer for driver core so CC him.
