[ Upstream commit ba18dad0fb880cd29aa97b6b75560ef14d1061ba ]
platform_get_irq() returns negative error number instead 0 on failure. And the doc of platform_get_irq() provides a usage example:
int irq = platform_get_irq(pdev, 0); if (irq < 0) return irq;
Fix the check of return value to catch errors correctly.
