The function hda_tegra_first_init() neglects to check the return value after executing platform_get_irq().

hda_tegra_first_init() should check the return value (if negative error number) for errors so as to not pass a negative value to the devm_request_irq().

Fix it by adding a check for the return value irq_id.
