[PATCH] net: marvell: fix a missing check of acpi_match_device

When acpi_match_device fails, its return value is NULL. Directly using the return value without a check may result in a NULL-pointer dereference. The fix checks if acpi_match_device fails, and if so, returns -EINVAL. Signed-off-by: Kangjie Lu --- drivers/net/ethernet/marvell/mvpp2/mvpp2_main.c |
