Subject: irqchip/irq-pruss-intc: Do not check for 0 return after calling platform_get_irq()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d0afed833970808f141ed52fcc591998087f3a26;p=linux.git

irqchip/irq-pruss-intc: Do not check for 0 return after calling platform_get_irq()

It is not possible for platform_get_irq() to return 0. Use the
return value from platform_get_irq().
