[PATCH] drivers/hwmon/*: kfree() correct pointers
The adm9240 driver, in adm9240_detect(), allocates a structure. The
error path attempts to kfree() ->client field of it (second one),
resulting in an oops (or slab corruption) if the hardware is not present.
->client field in adm1026, adm1031, smsc47b397 and smsc47m1 is the first in
${HWMON}_data structure, but fix them too.
