SRU justification for linux-firmware for Jaunty (applies to linux-
firmware-nonfree for karmic, but I believe it's not necessary because
the -nonfree package resides in multiverse):

Impact: The current package ships with corrupt firmware for Hauppauge
HVR-4000 tuner cards. The firmware does not pose a physical device
hazard, but usage of the device is prevented by the corrupt firmware.
When the correct firmware is used the device works properly

Addressed: The latest linux-firmware-nonfree package (which was split
from linux-firmware in Karmic) for Lucid version 1.7 replaces the
incorrect firmware with the correct firmware, verified by md5sum against
the firmware listed in [1]. However, this firmware is incompatible with
the kernel shipping in Jaunty and Karmic. Thus, a previous version of
the firmware has been used, verified again by md5sum against the
firmware listed in [1].

Minimal Patch: Change is not diff'able. The dvb-fe-cx24116.fw file was
replaced with a fixed version.

Reproduction: Load the v4l-dvb drivers on a machine with affected
hardware. Drivers will fail to load the firmware because it is
corrupted. Device will fail to work properly.

Regression Potential: Minimal because this change merely replaces one
broken firmware file with another. Worst-case scenario is people still
fail to use their devices due to incorrect firmware.
