The description of this patch explains why you would like to change this
code but not why this change is useful. Does building the current code
e.g. trigger a compiler warning ? If so, which warning ? If not, why
would you like to change this code and why do you think this change is
an improvement ?

the code will not fail in its urrent form but it will trigger
static code chekcers (actually this was found by a static code checker)
so its a QA issue not a bug fix in any way.
thx!

Notice that 'res' here is still incorrectly defined as an 'int', instead
of 'unsigned long'.
I've updated your patch to use the proper type for res, and added a
short commit log to describe what it's doing.
Merged into target-pending/for-next.
Thanks!
