------------------

From: Jurgen Kramer <gtmkramer at xs4all.nl>

commit 551c33e729f654ecfaed00ad399f5d2a631b72cb upstream.

Increase si2168 cmd execute timeout to prevent firmware load failures. Tests
shows it takes up to 52ms to load the 'dvb-demod-si2168-a30-01.fw' firmware.
Increase timeout to a safe value of 70ms.
