ASoC: spear: fix error return code in spdif_in_probe()
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.
