Jiasheng Jiang c154574b84 staging: greybus: audio: Check null pointer ... [ Upstream commit 2e81948177 ] As the possible alloc failure of devm_kcalloc(), it could return null pointer. Therefore, 'strings' should be checked and return NULL if alloc fails to prevent the dereference of the NULL pointer. Also, the caller should also deal with the return value of the gb_generate_enum_strings() and return -ENOMEM if returns NULL. Moreover, because the memory allocated with devm_kzalloc() will be freed automatically when the last reference to the device is dropped, the 'gbe' in gbaudio_tplg_create_enum_kctl() and gbaudio_tplg_create_enum_ctl() do not need to free manually. But the 'control' in gbaudio_tplg_create_widget() and gbaudio_tplg_process_kcontrols() has a specially error handle to cleanup. So it should be better to cleanup 'control' when fails.
