Hi Rusty,
DVB code uses symbol_get/symbol_put functions at module.c to allow
dynamically add frontend modules (responsible for tuning and
demodulating the digital signal). The problem is that symbol_get doesn't
properly mark the module that requested it.
Trent worked on a fix for this, by using 3 patches. One on module.c,
another on mtd driver, and the last one on linux-dvb.
With the patch, lsmod produces output like this:
cx88_dvb 14084 0
or51132 9988 1 cx88_dvb
Without it, this is what you get:
cx88_dvb 14084 0
or51132 9988 1
