Subject: ata: ahci_xgene: dereferencing uninitialized pointer in probe
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 8134233e8d346aaa1c929dc510e75482ae318bce upstream.
If the call to acpi_get_object_info() fails then "info" hasn't been
initialized. In that situation, we already know that "version" should
be XGENE_AHCI_V1 so we don't actually need to dereference "info".
Fixes: c9802a4be661 ('ata: ahci_xgene: Add AHCI Support for 2nd HW version of APM X-Gene SoC AHCI SATA Host controller.')
