From: QintaoShen <unSimple1993@xxxxxxx> [ Upstream commit ba56291e297d28aa6eb82c5c1964fae2d7594746 ] The allocation funciton devm_kcalloc may fail and return a null pointer, which would cause a null-pointer dereference later. It might be better to check it and directly return -ENOMEM just like the usage of devm_kcalloc in previous code.
