Subject: [media] mb86a20s: Fix estimate_rate setting
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f1b0c8217fd9507531152c0d6c12253e2e4e22bd;p=linux-beck.git

[media] mb86a20s: Fix estimate_rate setting

As reported by Dan Carpenter <dan.carpenter@oracle.com>:

	Smatch warnings:
	drivers/media/dvb-frontends/mb86a20s.c:644 mb86a20s_layer_bitrate() error: buffer overflow 'state->estimated_rate' 3 <= 3

What happens there is that estimate_rate index should be the layer
number, and not the guard interval.
