4.4-stable review patch. If anyone has any objections, please let me know. ------------------ [ Upstream commit 27d30400c448264c1ac9434cb836de0c230af213 ] platform_get_irq() returns an error code, but the spdif_in 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 error message and propagate the return value of platform_get_irq on failure.
