4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Brad Love <b...@nextdimension.cc> [ Upstream commit 779c79d4b833ec646b0aed878da38edb45bbe156 ] Hauppauge produced a revision of ImpactVCBe using an 888, with a 25MHz crystal, instead of using the default third overtone 50Mhz crystal. This overrides that frequency so that the cx25840 is properly configured. Without the proper crystal setup the cx25840 cannot load the firmware or decode video.
