Description

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

media: saa7164: add ioremap return checks and cleanups

Add checks for ioremap return values in saa7164_dev_setup(). If ioremap for BAR0 or BAR2 fails, release the already allocated PCI memory regions, remove the device from the global list, decrement the device count, and return -ENODEV.

This prevents potential null pointer dereferences and ensures proper cleanup on memory mapping failures.
