drm/amdgpu: drop retry loop in amdgpu_hmm_range_get_pages

2026-06-19T11:50:58+00:00

commit 342981fff32802a819d6fc7cf3c9fedf9f3d9d60 upstream. Since commit c08972f55594 ("drm/amdgpu: fix amdgpu_hmm_range_get_pages") moved mmu_interval_read_begin() out of the per-chunk loop, the captured notifier_seq is no longer refreshed across retries. As a result, the existing -EBUSY retry path can never make progress: hmm_range_fault() returns -EBUSY only when mmu_interval_check_retry(notifier, notifier_seq) reports that the sequence is stale. Once the sequence has advanced, the stored seq will never match again, so every subsequent call within the same invocation returns -EBUSY immediately. The "goto retry" therefore degenerates into a busy spin that simply burns CPU for the full HMM_RANGE_DEFAULT_TIMEOUT (~1s) window before finally bailing out with -EAGAIN. This is pure latency with no chance of recovery, and it actively hurts the KFD userptr stack: the caller ends up blocked for a second while holding mmap_lock, only to return -EAGAIN to the restore worker (or to userspace) which would have re-driven the operation immediately anyway. Drop the retry/timeout entirely and let -EBUSY propagate straight to out_free_pfns, where it is already translated to -EAGAIN. Recovery is handled at a higher level: the KFD restore_userptr_worker reschedules itself, and the userptr ioctl path returns -EAGAIN to userspace. No functional regression: the previous behaviour on -EBUSY was already to fail with -EAGAIN after a 1s stall; we just skip the stall.

HID: Input: Add battery list cleanup with devm action

2026-06-19T11:50:58+00:00

commit 426e5846eba75feaf1c9c6c119cb153610192da1 upstream. The batteries list (hdev->batteries) is not cleaned up during hidinput_disconnect(), but struct hid_battery entries are allocated with devm_kzalloc. When a driver is unbound (e.g. during devicereprobe), devm frees those entries while their list_head nodesremain dangling in hdev->batteries, which persists across rebinds.

driver core: reject devices with unregistered buses

2026-06-19T11:50:57+00:00

commit 36f35b8df6972167102a1c3d4361e0afb6a84534 upstream. Trying to register a device on a bus which has not yet been registered used to trigger a NULL-pointer dereference, but since the const bus structure rework registration instead succeeds without the device being added to the bus. This specifically means that the device will never bind to a driver and that the bus sysfs attributes are not created (i.e. as if the device had no bus). Reject devices with unregistered buses to catch any callers that get the ordering wrong and to handle bus registration failures more gracefully.

driver core: faux: fix root device registration

2026-06-19T11:50:57+00:00

commit 580a795105dae2ef1622df72a27a8fb0605e2f6b upstream. A recent change made the faux bus root device be allocated dynamically but failed to provide a release function to free the memory when the last reference is dropped (on theoretical failure to register the device or bus). Fix this by using root_device_register() instead of open coding. Also add the missing sanity check when registering faux devices to avoid use-after-free if the bus failed to register (which would previously have triggered a bunch of use-after-free warnings).
