I have the impression that the web interface of git.kernel.org may have
a problem with serving binary files. Try to obtain the firmware using
git; in my case this yields a different firmware.fw file. (I cannot test
any of the files, though.)
To get the firmwware file with git, you need the "git-core" package.
Then you can cd to a convenient working directory - you will need about
2.8 MB of disk space - and do this (as your normal user):
git clone git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware-from-kernel.git
If that command is successful then you will find the firmware at
./linux-firmware-from-kernel/vicam/firmware.fw
Copy this file to /lib/firmware/vicam/firmware.fw and try to load the
vicam kernel module again.
