Subject: [PATCH] ALSA: arm: pxa: pxa2xx-ac97-lib: fix return value check of
platform_get_irq()
platform_get_irq() returns negative error number on failure, fix the
return value check in pxa2xx_ac97_hw_probe() and assign the error code
to 'ret'.
Fixes: 2548e6c76ebf ("ARM: pxa: pxa2xx-ac97-lib: use IRQ resource")
