soc: amlogic: canvas: fix device leak on lookup

2026-01-11T14:18:57+00:00

commit 32200f4828de9d7e6db379909898e718747f4e18 upstream. Make sure to drop the reference taken to the canvas platform device when looking up its driver data. Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference. Also note that commit 28f851e6afa8 ("soc: amlogic: canvas: add missing put_device() call in meson_canvas_get()") fixed the leak in a lookup error path, but the reference is still leaking on success.

drivers: meson: secure-pwrc: always enable DMA domain

[ Upstream commit 0bb4644d583789c97e74d3e3047189f0c59c4742 ] Starting from commit e45f243409db ("firmware: meson_sm: populate platform devices from sm device tree data") pwrc is probed successfully and disables unused pwr domains. By A1 SoC family design, any TEE requires DMA pwr domain always enabled.
