[PATCH 5.8 480/633] soc: xilinx: Fix error code in zynqmp_pm_probe()

[Greg Kroah-Hartman]

From: Dan Carpenter <dan.carpen...@oracle.com>

[ Upstream commit a6f2f0fdc73aacc6e10ae48ae78634dba26702d4 ]

This should be returning PTR_ERR() but it returns IS_ERR() instead.

Fixes: ffdbae28d9d1 ("drivers: soc: xilinx: Use mailbox IPI callback")
