Actually there are four instances of this:
drivers/accel/habanalabs/gaudi/gaudi.c:1036 _gaudi_init_tpc_mem() error:
dereferencing freed memory 'cb->buf' (line 1035)
drivers/accel/habanalabs/gaudi/gaudi.c:5654 gaudi_memset_device_memory() error:
dereferencing freed memory 'cb->buf' (line 5653)
drivers/accel/habanalabs/gaudi/gaudi.c:5717 gaudi_memset_registers() error:
dereferencing freed memory 'cb->buf' (line 5716)
drivers/accel/habanalabs/goya/goya.c:4820 goya_memset_device_memory() error:
dereferencing freed memory 'cb->buf' (line 4819)
