That means that if you have parts of your driver\nthat aren't using devm or are using \"roll your own\" devm w/\ndevm_add_action_or_reset() you need to keep that in mind.\n\nThe mt8186 audio driver didn't quite get this right. Specifically, in\nmt8186_init_clock() it called mt8186_audsys_clk_register() and then\nwent on to call a bunch of other devm function. The caller of\nmt8186_init_clock() used devm_add_action_or_reset() to call\nmt8186_deinit_clock() but, because of the intervening devm functions,\nthe order was wrong.\n\nSpecifically at probe time, the order was:\n1. mt8186_audsys_clk_register()\n2. afe_priv->clk = devm_kcalloc(...)\n3. afe_priv->clk[i] = devm_clk_get(...)\n\nAt remove time, the order (which should have been 3, 2, 1) was:\n1. mt8186_audsys_clk_unregister()\n3. Free all of afe_priv->clk[i]\n2. Free afe_priv->clk\n\nThe above seemed to be causing a use-after-free. Luckily, it's easy to\nfix this by simply using devm more correctly. Let's move the\ndevm_add_action_or_reset() to the right place. In addition to fixing\nthe use-after-free, code inspection shows that this fixes a leak\n(missing call to mt8186_audsys_clk_unregister()) that would have\nhappened if any of the syscon_regmap_lookup_by_phandle() calls in\nmt8186_init_clock() had failed."}],"metrics":{},"references":[{"url":"https://git.kernel.org/stable/c/3e56a1c04882852e3e7d6c59756a16211ebbc457","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/a93d2afd3f77a7331271a0f25c6a11003db69b3c","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/dffd9e2b57cb845930fa885aa634a847ba2130dd","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"}]}}]}
