Subject: [PATCH] staging: vchiq_arm: Use devm_kzalloc() for vchiq_arm_state
allocation

The struct vchiq_arm_state 'platform_state' is currently allocated dynamically using kzalloc(). Unfortunately, it is never freed and is subjected to memory leaks in the error handling paths of the probe() function.

To address the issue, use device resource management helper devm_kzalloc(), to ensure cleanup after its allocation.
