Description
Description
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix rmmio iounmap skipped on device removal
amdgpu_pci_remove() calls drm_dev_unplug() before fini_sw(), so
drm_dev_enter() is already false there and the iounmap() guarded by it
is skipped. This .remove path runs on both hot-unplug and plain rmmod,
so the register BAR ioremap mapping leaks one instance per unload.
Unmap rmmio unconditionally (guard only on non-NULL) and drop the now
unused idx.
(cherry picked from commit dd6f86a97260e5207d3329ad03aa89fdad61b1e6)
