+Subject: [PATCH] w1: ds2482: cosmetic fixes after 54865314f5a1
+
+commit 5cb27d30fc3a281e830a2099d520b469e2b82008 upstream.
+
+We have a helper function ds2482_calculate_config() which is calculating
+the config value, so just use it instead of passing the same variable
+in all calls to this function.
+
+Also fixes the placement of module parameters to match with:
