>Subject: [patch] megaraid_sas: harmless memory corruption in
>megasas_mgmt_fw_ioctl()
>
>The intent here was for the "kbuff_arr[i] = NULL;" to be inside the loop
but,
>because the curly braces were missing, it's after the loop.
>This means we corrupt a little memory one step beyond the array.
>Fortunately, we weren't going to use that memory anyway so it's harmless.
>Also we aren't going to use kbuff_arr[] again so we don't need to set it
to
>NULL.
