soc: amlogic: canvas: fix device leak on lookup

2026-01-08T09:14:29+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.

soc: amlogic: Explicitly include correct DT includes

2023-08-04T13:18:42+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
