On contention,\nww_mutex_lock() returns -EDEADLK, which is the caller's signal to drop\nthe lock it holds and retry the acquisition in the canonical order.\n\nHowever, regulator_lock_two() tests the return value against -EDEADLOCK\nrather than -EDEADLK. On most architectures, EDEADLK and EDEADLOCK are\nthe same value, so the comparison happens to be correct and the bug is\ninvisible. But on MIPS, SPARC, and PowerPC, those two errors have\ndifferent values. The test is wrong: a genuine -EDEADLK backoff no\nlonger matches -EDEADLOCK, so instead of unlocking and retrying, the\ncode falls into WARN_ON(ret) and returns with only one of the two\nregulators locked.\n\nIn practice, this is a bug only on MIPS, because the regulator core is\nnot built or used on the other two platforms.\n\nIn general, EDEADLK is preferred over EDEADLOCK for new code.","state":0,"publishedAt":"2026-08-15T05:55:29.118+00:00","modifiedAt":"2026-10-16T18:55:16.999+00:00","affected":[{"ecosystem":"Vendor
