cpufreq: dt/dt-platdev: eliminate uses of of_node_put()

[PATCH 0/2] cpufreq: dt/dt-platdev: eliminate uses of of_node_put()

Posted by Javier Carrasco 1 week, 4 days ago

This series removes uses of of_node_put() in dt and dt-platdev, which
can be replaced with the clenaup handler introduced with
54da6a092431 ("locking: Introduce __cleanup() based infrastructure").

This change provides a scope-based cleanup mechanism to avoid potential
memory leaks that can appear if of_node_put() is not used correctly.

The series is based on linux-next (next-20240422) and has been validated
with a Rockchip RK3568 that makes use of these drivers.
