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.
