Subject: firmware: arm_sdei: Fix return value check in sdei_present_dt()
Git-commit: 2f7aacf795e0192648b51674aef90e755e02408c
Patch-mainline: v4.16-rc1
References: fate#326420 fate#325360
In case of error, the function of_platform_device_create() returns
NULL pointer not ERR_PTR(). The IS_ERR() test in the return value
check should be replaced with NULL test.
Fixes: 677a60bd2003 ("firmware: arm_sdei: Discover SDEI support via ACPI")
