is there are reason not to address review comments?

	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 address in next patch

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

> +	u8 rlen = 0x02;
> +	struct edl_event_hdr *edl;

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.
