Subject: media: dvb_ca_en50221: Increase timeout for link init
Author: Ralph Metzler <r...@metzlerbros.de>
Date: Sun Jun 25 18:37:06 2017 -0300
Some CAMs do a really slow initialization, which requires a longer timeout
for the first response.
Original code change by Ralph Metzler, modified by Jasmin Jessich to match
Kernel code style.
