From da55b1ad4b29b6ab44d5dc8ea8306260246d2699 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 3 Jul 2017 07:59:26 -0500 Subject: PM / devfreq: rk3399_dmc: fix error return code in rk3399_dmcfreq_probe() platform_get_irq() returns an error code, but the rk3399_dmc driver ignores it and always returns -EINVAL. This is not correct, and prevents -EPROBE_DEFER from being propagated properly. Notice that platform_get_irq() no longer returns 0 on error: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af Print and propagate the return value of platform_get_irq on failure.
