cpufreq: sti: avoid NULL dereference in dev_err()

2026-09-02T04:15:44+00:00

ddata.cpu is NULL-checked, then immediately passed to dev_err(). Replace with pr_err() to avoid dereferencing NULL. Fixes: ab0ea257fc58 ("cpufreq: st: Provide runtime initialised driver for ST's platforms") Signed-off-by: Xueqin Luo Signed-off-by: Viresh Kumar

cpufreq: Use of_property_present()

2024-08-07T06:41:45+00:00

Use of_property_present() to test for property presence rather than of_(find|get)_property(). This is part of a larger effort to remove callers of of_find_property() and similar functions. of_find_property() leaks the DT struct property and data pointers which is a problem for dynamically allocated nodes which may be freed.

cpufreq: Explicitly include correct DT includes

2023-07-20T10:31:57+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. Signed-off-by: Rob Herring Acked-by: Rafael J.
