That's due the need of including pinctrl.h header and because

The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So the driver needs to export the I2C table and this
be built into the module or udev won't have the necessary information

This patch adds support for the c8sectpfe input HW found on
STiH407/410 SoC's.

It currently supports the TS input block, memdma engine
and hw PID filtering blocks of the C8SECTPFE subsystem.

The driver creates one LinuxDVB adapter, and a
demux/dvr/frontend set of devices for each tsin channel
which is specificed in the DT. It has been tested with
multiple tsin channels tuned, locked, and grabbing TS
simultaneously.

The B2100A dvb NIM card from ST has 2x stv0367 demodulators
and 2x TDA18212 silicon tuners, with a 16Mhz crystal. To

to add support for the 16Mhz reference clock.

When using stv0367 demodulator with STi STB platforms,
we can have easily have four or more stv0367 demods running
in the system at one time.

As typically the b2120 reference design ships with a b2004a daughter
board, which can accept two dvb NIM cards, and each b2100A NIM
has 2x stv0367 demods and 2x NXPs tuner on it.

In such circumstances it is useful to print the i2c address
on error messages to know which one is failing due to I2C issues.

use variable-length arrays, as complained by smatch:
        drivers/media/dvb-frontends/horus3a.c:57:19: warning: Variable length array is used.

The max usecase of the driver seems to be 10 bytes + 1 for the

So, let's be safe and allocate 11 bytes for the write buffer.
This should be enough to cover all cases. If not, let's print
