I suggest to improve the provided information. How do you think about a wording variant like the following? The function “msm_gpu_crashstate_capture” can be called multiple times. The members “comm”, “cmd” and “bos” of the data structure “msm_gpu_state” are reassigned with pointers according to dynamic memory allocations if the preprocessor symbol “CONFIG_DEV_COREDUMP” was defined. But the function “kfree” was not called for them before. Thus add missing actions. * Release previous objects. * Use further null pointer checks. * Complete the corresponding exception handling.
