[PATCH v2 2/3] drm/xe: Allow the pm notifier to continue on failure

by Thomas Hellström

Its actions are opportunistic anyway and will be completed on device suspend. Marking as a fix to simplify backporting of the fix that follows in the series. v2: - Keep the runtime pm reference over suspend / hibernate and document why.

[PATCH net v4] selftests: net: add test for destination in broadcast packets

Add test to check the broadcast ethernet destination field is set correctly. This test sends a broadcast ping, captures it using tcpdump and ensures that all bits of the 6 octet ethernet destination address are correctly set by examining the output capture file.

[PATCH v3] mfd: intel_soc_pmic_chtdc_ti: Set use_single_read regmap_config flag

[PATCH] wifi: iwlwifi: Fix dentry reference leak in iwl_mld_add_link_debugfs

by Miaoqian Lin

The debugfs_lookup() function increases the dentry reference count. Add missing dput() call to release the reference when the "iwlmld" directory already exists.
