[PATCH v3] pmdomain: imx: Fix reference count leak in imx_gpc_probe()

by Wentao Liang

of_get_child_by_name() returns a node pointer with refcount incremented. Use the __free() attribute to manage the pgc_node reference, ensuring automatic of_node_put() cleanup when pgc_node goes out of scope. This eliminates the need for explicit error handling paths and avoids reference count leaks.

[PATCH iwl-net v1] ixgbevf: fix link setup issue

by Jedrzej Jagielski

It may happen that VF spawned for E610 adapter has problem with setting link up. This happens when ixgbevf supporting mailbox API 1.6 coopearates with PF driver which doesn't support this version of API, and hence doesn't support new approach for getting PF link data. In that case VF asks PF to provide link data but as PF doesn't support it, returns -EOPNOTSUPP what leads to early bail from link configuration sequence. Avoid such situation by using legacy VFLINKS approach whenever negotiated API version is less than 1.6.

[PATCH v3 02/22] drm/pagemap, drm/xe: Ensure that the devmem allocation is idle before use

by Thomas Hellström

In situations where no system memory is migrated to devmem, and in upcoming patches where another GPU is performing the migration to the newly allocated devmem buffer, there is nothing to ensure any ongoing clear to the devmem allocation or async eviction from the devmem allocation is complete. Address that by passing a struct dma_fence down to the copy functions, and ensure it is waited for before migration is marked complete. v3: - New patch.
