If it fails early enough, before xhci->interrupters\nis allocated but after xhci->max_interrupters has been set, which\nhappens in most (all?) cases, things get uglier, as xhci_mem_cleanup()\nunconditionally derefences xhci->interrupters. With prejudice.\n\nGate the interrupt freeing loop with a check on xhci->interrupters\nbeing non-NULL.\n\nFound while debugging a DMA allocation issue that led the XHCI driver\non this exact path.\n\ud83d\udccf Published: 2024-09-11T15:13:59.032Z\n\ud83d\udccf Modified: 2025-05-09T08:06:06.586Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/3efb29f6a78d4746f958c1ab6cd7981c5762f03b\n2. https://git.kernel.org/stable/c/770cacc75b0091ece17349195d72133912c1ca7c\n3. https://git.kernel.org/stable/c/dcdb52d948f3a17ccd3fce757d9bd981d7c32039", "creation_timestamp": "2025-05-09T08:25:26.000000Z"}
