Subject: [media] mb86a20s: Fix estimate_rate setting
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b1f89331190820c42397156063fe5e39bc514e3b;p=openwrt%2Fstaging%2Fblogic.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.
