Subject: [PATCH AUTOSEL for 4.9 236/293] ipmi/powernv: Fix error return code
 in ipmi_powernv_probe()

From: Wei Yongjun <weiyongjun1@...wei.com>

[ Upstream commit e749d328b0b450aa78d562fa26a0cd8872325dd9 ]

Fix to return a negative error code from the request_irq() error
handling case instead of 0, as done elsewhere in this function.
