## Description

In the Linux kernel, the following vulnerability has been resolved:  wifi: mt76: mt7921: fix resource leak in probe error path  When pcim_iomap_region() or devm_kmemdup() fail, the code returns directly without cleaning up previously allocated resources:   - mt76_device allocated by mt76_alloc_device()   - pci irq vectors allocated by pci_alloc_irq_vectors() Fix this by jumping to the existing error cleanup path instead of returning directly.
