[PATCH 6.6 58/82] staging: vchiq_arm: Use devm_kzalloc() for vchiq_arm_state allocation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit 404b739e895522838f1abdc340c554654d671dde ]

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.
