CVE-2026-89877

media: saa7164: fix cleanup on resource allocation failure

In the Linux kernel, the following vulnerability has been resolved:

media: saa7164: fix cleanup on resource allocation failure

saa7164_dev_setup() adds the device to the global saa7164_devlist before
requesting the PCI BAR memory regions.

If get_resources() fails, saa7164_dev_setup() decrements the device count
and returns an error, but leaves the device on saa7164_devlist. The probe
error path then frees the device, leaving a dangling entry on the global
list.

Reuse the existing MMIO mapping error path to remove the device from
saa7164_devlist and decrement the device count before returning.

Also release BAR0 if it was successfully requested but the BAR2 request
fails.
