Description

In the Linux kernel, the following vulnerability has been resolved:\nthermal: intel: int340x: processor: Fix warning during module unload\nThe processor_thermal driver uses pcim_device_enable() to enable a PCI\ndevice, which means the device will be automatically disabled on driver\ndetach. Thus there is no need to call pci_disable_device() again on it.\nWith recent PCI device resource management improvements, e.g. commit\nf748a07a0b64 ('PCI: Remove legacy pcim_release()'), this problem is\nexposed and triggers the warining below.\n[ 224.010735] proc_thermal_pci 0000:00:04.0: disabling already-disabled device\n[ 224.010747] WARNING: CPU: 8 PID: 4442 at drivers/pci/pci.c:2250 pci_disable_device+0xe5/0x100\n...\n[ 224.010844] Call Trace:\n[ 224.010845] \n[ 224.010847] ? show_regs+0x6d/0x80\n[ 224.010851] ? __warn+0x8c/0x140\n[ 224.010854] ? pci_disable_device+0xe5/0x100\n[ 224.010856] ? report_bug+0x1c9/0x1e0\n[ 224.010859] ? handle_bug+0x46/0x80\n[ 224.010862] ? exc_invalid_op+0x1d/0x80\n[ 224.010863] ? asm_exc_invalid_op+0x1f/0x30\n[ 224.010867] ? pci_disable_device+0xe5/0x100\n[ 224.010869] ? pci_disable_device+0xe5/0x100\n[ 224.010871] ? kfree+0x21a/0x2b0\n[ 224.010873] pcim_disable_device+0x20/0x30\n[ 224.010875] devm_action_release+0x16/0x20\n[ 224.010878] release_nodes+0x47/0xc0\n[ 224.010880] devres_release_all+0x9f/0xe0\n[ 224.010883] device_unbind_cleanup+0x12/0x80\n[ 224.010885] device_release_driver_internal+0x1ca/0x210\n[ 224.010887] driver_detach+0x4e/0xa0\n[ 224.010889] bus_remove_driver+0x6f/0xf0\n[ 224.010890] driver_unregister+0x35/0x60\n[ 224.010892] pci_unregister_driver+0x44/0x90\n[ 224.010894] proc_thermal_pci_driver_exit+0x14/0x5f0 [processor_thermal_device_pci]\n...\n[ 224.010921] ---[ end trace 0000000000000000 ]---\nRemove the excess pci_disable_device() calls.\n[ rjw: Subject and changelog edits ]
