soc: mediatek: svs: Fix memory leak in svs_enable_debug_write()

2026-03-04T12:19:36+00:00

[ Upstream commit 6259094ee806fb813ca95894c65fb80e2ec98bf1 ] In svs_enable_debug_write(), the buf allocated by memdup_user_nul() is leaked if kstrtoint() fails. Fix this by using __free(kfree) to automatically free buf, eliminating the need for explicit kfree() calls and preventing leaks.

soc/mediatek: mtk-devapc: Convert to platform remove callback returning void

2025-02-27T12:10:46+00:00

[ Upstream commit a129ac3555c0dca6f04ae404dc0f0790656587fb ] The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

soc: mediatek: Explicitly include correct DT includes

2023-08-12T08:31:01+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.
