Robert Richter a0a4643f18 EDAC/mc: Fix edac_mc_find() in case no device is found ... [ Upstream commit 29a0c84397 ] The function should return NULL in case no device is found, but it always returns the last checked mc device from the list even if the index did not match. Fix that. I did some analysis why this did not raise any issues for about 3 years and the reason is that edac_mc_find() is mostly used to search for existing devices. Thus, the bug is not triggered.
