media: [RESEND] media: dvb-frontends: Add delay to Si2168 restart
On faster CPUs a delay is required after the resume command and the
restart command. Without the delay, the restart command often returns
-EREMOTEIO and the Si2168 does not restart. Note that this patch fixes
the same issue as https://patchwork.linuxtv.org/patch/44304/, but I
believe my udelay() fix addresses the actual problem.

Yes, you are likely correct!
Patch is already applied, but however I think it should be something
like usleep_range(100, ~0) in order to allow scheduler optimize
resources as upper limit of delay is not critical at all. See
