bttv driver not working after kernel-update to 2.6.32-24.41 and 2.6.32-24.42

[Jeroen Venneman]

After update to 2.6.32-24.41 and 2.6.32-24.42 the bttv driver stopped working, it doesn detect my bt878 tv card anymore.
When I boot a previous kernel eg. 2.6.32-23.37 the tv card works OK.
See dmesg outputs below, first the working one, with 2.6.32-23.37:

Then after updating to 2.6.32-24.42:

[ 12.842658] bttv: Unknown symbol ir_input_keydown

Looks like bttv is broken or doesn't match with the new kernel.
Any idea?

Current system is 2.6.32-24-generic #42-Ubuntu SMP Fri Aug 20 14:21:58 UTC 2010 x86_64 GNU/Linux

If more details are necessary please let me know.
Thanks.

Updated to kernel 2.6.32-25-generic #43, this solved the problem, see part of dmesg below:

[ 13.830817] Linux video capture interface: v2.00
[ 13.854146] bttv: driver version 0.9.18 loaded
[ 13.854149] bttv: using 8 buffers with 2080k (520 pages) each for capture
[ 13.854240] bttv: Bt8xx card found (0).

[ 13.854271] bttv 0000:03:06.0: PCI INT A -> GSI 20 (level, low) -> IRQ 20
[ 13.854285] bttv0: Bt878 (rev 17) at 0000:03:06.0, irq: 20, latency: 32, mmio: 0xfdcff000

[ 13.854325] bttv0: using: Terratec TerraTValue Version Bt878 [card=33,autodetected]

So problem solved, no further action necessary.
