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.

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.

Just like with the s5h1411, the s5h1409 needs a soft-reset in order for it
to know that the tuner has been told to change frequencies.  This change
changes the behavior from "random tuning times between 500ms to complete
tuning lock failures" to "tuning lock consistently within 700ms".

Appears to be resolved by dropping zig-zag tuning and relying on
hardware only:

> szap-s2 -r -c 39.FTATV "1=Pgm1;Net1"
reading channels from file '39.FTATV'
zapping to 3 '1=Pgm1;Net1':
delivery DVB-S, modulation QPSK
sat 0, frequency 11140 MHz V, symbolrate 1425000, coderate 5/6, rolloff 0.35

status 1f | signal ff80 | snr c199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

Tuning to a weaker channel shows that the hardware recovers sync:

status 1f | signal fe40 | snr 5199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 03 | signal fd40 | snr 5000 | ber 00000000 | unc 00000000 |
