Subject[PATCH 5/5 v3] ASoC: intel: mfld: Handle return value of platform_get_irq
Date
platform_get_irq() can fail here and we must check its return value.

Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com>

changes in v2 :
Add failure case '<= 0' instead of '< 0'. IRQ0 is not valid.
changes in v3 :
Return EIO insted of ctx->irq_num.
