## Description

In the Linux kernel, the following vulnerability has been resolved:  ata: libata-transport: fix error handling in ata_tport_add()  In ata_tport_add(), the return value of transport_add_device() is not checked. As a result, it causes null-ptr-deref while removing the module, because transport_remove_device() is called to remove the device that was not added.  Unable to handle kernel NULL pointer dereference at virtual address 00000000000000d0 CPU: 12 PID: 13605 Comm: rmmod Kdump: loaded Tainted: G        W          6.1.0-rc3+ #8 pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : device_del+0x48/0x39c lr : device_del+0x44/0x39c Call trace:  device_del+0x48/0x39c  attribute_container_class_device_del+0x28/0x40  transport_remove_classdev+0x60/0x7c  attribute_container_device_trigger+0x118/0x120  transport_remove_device+0x20/0x30  ata_tport_delete+0x34/0x60 [libata]  ata_port_detach+0x148/0x1b0 [libata]  ata_pci_remove_one+0x50/0x80 [libata]  ahci_remove_one+0x4c/0x8c [ahci]  Fix this by checking and handling return value of transport_add_device() in ata_tport_add().
