Comment (by warpme@…):

 This patch makes sure reset disecq bus only once if SCR system is used.
 Originally disecq.cpp does disecq microcontroler reset (e0 00 00) for
 every phy card. So there is situation where card1 does reset diseq, set
 LNB_SCR_VCO1, next, card2 does reset diseq, set  LNB_SCR_VCO2, etc. As
 disecq microcontroller at LNB is shared, there is potential issue as next
 disecq microcontroller reset impacts previous LNB_SCR_VCOx setting. Issue
 can manifest when i.e LiveTV last channel is the same like starting
 channel in DB and #10997 is applied. In such case user can experience
 issues with first launch of LiveTV after BE start on all tuners except
 last one. Attached patch makes sure disecq microcontroler reset (e0 00 00)
 is sent only once for SCR disecq busses. For non-SCR disecq busses, disecq
 microcontroler reset behavior is unchanged.
