Subject: drm/bridge: ti-sn65dsi86: zero is never greater than an unsigned int
Git-commit: 2f8fcc7794c147fbb6c0b0e2e4d65876034ff874
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
When we iterate over ti_sn_bridge_dp_rate_lut, there's no reason to
start at index 0 which always contains the value 0. 0 is not a valid
link rate.
This change should have no real effect but is a small cleanup.
