Re: Hauppauge WinTV-HVR2205 driver feedback

Sorry If I've posted this to the wrong section my first attempt..

Hi
    I'm attempting to get an HVR2205 up and going.
CORE saa7164[1]: subsystem: 0070:f120, board: Hauppauge WinTV-HVR2205 
[card=13,autodetected]
Distribution is CentOS7 so I've pulled the v4l from media_build.git
Had to change a couple of things..  and another macro issue regarding 
clamp() ..
Seems the kzalloc(4 * 1048576, GFP_KERNEL) in saa7164-fw.c  was failing..
kept getting:  kernel: modprobe: page allocation failure: order:10, 
mode:0x10c0d0
Have plenty of RAM free so surprised about that one.. tried some of the 
tricks re increasing the vm.min_free_kbytes etc..

Any way I modified the routine to only allocate a single chunk buffer 
based on dstsize and tweaked the chunk handling code..
seemed to fix that one.. fw downloaded and seemed to boot ok..

Next I'm running into a problem with the saa7164_dvb_register() stage...

saa7164[1]: Hauppauge eeprom: model=151609
saa7164_dvb_register() Frontend/I2C initialization failed
saa7164_initdev() Failed to register dvb adapters on porta

I added some extra debug and identified that client_demod->dev.driver is 
null..

However I'm now stuck as to what to tackle next..

I can provide more info, just didn't want to spam the list for my first 
email..

Regards
