[pvrusb2] Remote dies when upgrading to 2.6.38 from 2.6.36 on HVR-1900

[Nicholas Robbins]

Thanks Mike! 


You were exactly right, looks like all of the modules are now in the tree, and lirc just provides the user-space daemon and applications. Also, my key codes have changes and such, as the remote is now handled with the event driver rather than and i2c driver from the user-space perspective. If anyone needs help getting the remote to work with a newer kernel let me know, as I've gotten it sorted out. (At least for 2.6.38.6 and lirc 0.9.0 on gentoo)

LIRC doesn't depend on the V4L ioctl-based API.  It expects instead to 
install a kernel driver which ties into the I2C bus API exported by the 
bridge driver (e.g. pvrusb2).

However that I2C API has undergone some changes of late.  There have 
been some recent changes to the pvrusb2 driver within the kernel needed 
to stay in sync with these changes.  I'd be willing to bet that this is 
what has caused the problem.  This unfortunately creates issues for 
out-of-tree drivers when the kernel APIs they are using becomes a moving 
target.

Try looking for a later version of LIRC.  Odds are that a later release 
of the package already tracks this - or there very soon will be a 
release that will catch up.
