The kernel configuration lets you set the path, but it seems to be
ignored. I didn't check the code, I'm only observing based on the fact
that I set it to /etc in the config and the kernel still used /usr/lib.
 

The lines above - together with their #ifndef DVB_TDA1004X_FIRMWARE_FILE 
(...)
#endif context - look OK to me. Can you check whether there actually is 
a DVB_TDA...
definition in your .config?

Can somebody als enlighten me to the internal workings of 
request_firmware from
firmware_class.c? As I understand it, this procedure sets up a node 
somewhere in the
/sys hierarchy and then alerts the hotplug scripts to copy the firmware 
to that node.

However, request_firmware only ever receives a name for the firmware 
file that is
29 chars in length (it will truncate the rest, if I read the code 
correctly). That name
is definitely lacking a path, so how do the drivers actually pass the 
path to
request_firmware? Or don't they and the hotplug scripts look in their 
default
directory?

I'm sorry for the questions, but I just can't read firmware_class.c.

Sincerely,
Roland
