ld: Warning: size of symbol `debug' changed from 85 in arch/x86/kernel/built-in.o to 4 in drivers/built-in.o

It would also be Good if arch/x86/kernel/entry_32.S didn't have a

Hi there!

While having a look at the allocation of struct dvb_frontend in *_attach
functions, I found some cases calling memset after kzalloc. This is
redundant, and the attached patch removes these calls.
I also changed one case calling kmalloc and memset to kzalloc.

Regards

For i2c normal work, we need to slow down the bus speed. However, the
slow down breaks the eeprom firmware load. So, use normal speed for
eeprom booting and then restore the i2c speed after that.

It should also be noticed that no other I2C transfer should be in course
while booting from eeprom, otherwise, tda10046 goes into an instable
state. So, proper locking are needed at the i2c bus master.

Tested with saa7134 MSI TV @nyware A/D board, that comes with an eeprom
with firmware version 29.

The patch is nedded to add support for that card.

2. Fill set_voltage with actually control voltage code.
3. Correct set_tone to not affect voltage.
