been resolved:\n\ndrm/amdgpu: fix AMDGPU_INFO_READ_MMR_REG\n\nThere were multiple issues in that code.\n\nFirst of all the order between the reset semaphore and the mm_lock was\nwrong (e.g. copy_to_user) was called while holding the lock.\n\nThen we allocated memory while holding the reset semaphore which is also\na pretty big bug and can deadlock.\n\nThen we used down_read_trylock() instead of waiting for the reset to\nfinish.\n\n(cherry picked from commit 361b6e6b303d4b691f6c5974d3eaab67ca6dd90e)"}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus":
