is there are reason not to address review comments?
[Sai] : I will address in next patch

const u8 cmd[] = { EDL_PATCH_CONFIG_CMD, 0x01, 0, 0, 0 };

I missed these two and must have assumed there are used somewhere, rlen and rtype are a waste to be declared.
[Sai] : I will delete rlen in next patch.
