Subject: media: [RESEND] media: dvb-frontends: Add delay to Si2168 restart
From: Ron Economos <[email protected]>
[ Upstream commit 380a6c86457573aa42d27ae11e025eb25941a0b7 ]
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.
