The call chain is as follows: gk20a_clk_ctor() <- nvkm_clk_ctor() <- nvkm_notify_init() When nvkm_notify_init() returns -ENOMEM, all of its callers (and callers of callers) will be influenced if there is a failed kzalloc inside which. In this case, maybe we should check the return value of gk20a_clk_ctor() and release clk if it returns -ENOMEM. And many other functions also have the same issue (e.g., gm20b_clk_new_speedo0). Do you have any idea about this problem? Regards, Dinghao
