[alsa-devel] [PATCH] ASoC: fsl_ssi: Fix irq error check

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at freescale.com>

Commit 2ffa531078037a0 ("ASoC: fsl_ssi: Fix module unbound") changed the way to 
retrieve the irq number from irq_of_parse_and_map() to platform_get_irq(), but
missed to updated the irq error check accordingly.

We should test for negative irq number and propagate it in the case of error.
