pinctrl: sunxi: Fix memory leak on krealloc failure

2025-08-15T10:08:52+00:00

[ Upstream commit e3507c56cbb208d4f160942748c527ef6a528ba1 ] In sunxi_pctrl_dt_node_to_map(), when krealloc() fails to resize the pinctrl_map array, the function returns -ENOMEM directly without freeing the previously allocated *map buffer. This results in a memory leak of the original kmalloc_array allocation.

pinctrl: Explicitly include correct DT includes

2023-07-20T19:41:24+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.

pinctrl: sunxi: Add some defensiveness for regulators array

2023-07-20T19:32:36+00:00

The sunxi pinctrl has a fixed size array it uses to store regulators used in the driver. There is currently nothing that ensures that the number of elements in the array is large enough to map the regulators defined by the individual SoCs. While this is currently the case having an explicit check in there will make life easier for anyone debugging memory issues that manifest in the driver so let's add one.

pinctrl: Use of_property_present() for testing DT property presence

2023-03-23T08:28:38+00:00

It is preferred to use typed property access functions (i.e. of_property_read_ functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.
