APPLIED: [SRU][F/J:linux-bluefield][PATCH v1 0/2] UBUNTU: SAUCE: mlxbf-gige: Fix kernel panic after reboot

[Bartlomiej Zolnierkiewicz]

Applied to focal:linux-bluefield/master-next and
jammy:linux-bluefield/master-next.

While merging I've added " (part 1/2)" and " (part 2/2)" to the commit
summaries (they were identical so it was difficult to distinguish
commits).

Thanks.
