[PATCH 08/10 v3] Input: twl4030-pwrbutton: Handle return value of platform_get_irq

[Arvind Yadav]

platform_get_irq() can fail here and we must check its return value.

changes in v2 :
              return irq instead of -ENODEV.
changes in v3 :
              Add failure case '<= 0' instead of '< 0'. IRQ0 is not valid.
