Subject: [PATCH AUTOSEL 5.15 1/2] power: supply: cros_usbpd: provide ID table for avoiding fallback match

From: Tzung-Bi Shih <[email protected]>

[ Upstream commit 0f8678c34cbfdc63569a9b0ede1fe235ec6ec693 ]

Instead of using fallback driver name match, provide ID table[1] for the
primary match.

Subject: [PATCH AUTOSEL 5.15 2/2] iommu/arm-smmu-v3: Free MSIs in case of ENOMEM

From: Aleksandr Aprelkov <[email protected]>

[ Upstream commit 80fea979dd9d48d67c5b48d2f690c5da3e543ebd ]

If devm_add_action() returns -ENOMEM, then MSIs are allocated but not
not freed on teardown. Use devm_add_action_or_reset() instead to keep
the static analyser happy.
