staging: android: ion: tegra: Use devm_kcalloc instead of devm_kzalloc
Replace devm_kzalloc with devm_kcalloc to ensure there are no integer overflows from the multiplication of a number * sizeof. The following Coccinelle semantic patch was used to make this change: //<smpl> @@ expression dev,E1,E3; type T; @@ - devm_kzalloc(dev,E1*sizeof(T),E3) + devm_kcalloc(dev,E1,sizeof(T),E3) //</smpl> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
