Hans Verkuil 08debc1701 [media] si4713: fix Kconfig dependencies
The SI4713 select should be I2C_SI4713 and the USB driver needs to depend on
I2C as well.

Hans Verkuil 8aab72bb07 [media] si4713: si4713_set_rds_radio_text overwrites terminating \0
si4713_set_rds_radio_text will overwrite the terminating zero at the
end of the rds radio text string in order to send out a carriage return
as per the RDS spec.
Use a separate char buffer for the CR instead of corrupting the control
string.

Dinesh Ram cc6d618fdf [media] si4713: move supply list to si4713_platform_data
The supply list is needed by the platform driver, but not by the usb driver.
So this information belongs to the platform data and should not be hardcoded
in the subdevice driver.

Dinesh Ram e26fa6dccf [media] si4713: Bug fix for si4713_tx_tune_power() method in the i2c driver
In the si4713_tx_tune_power() method, the args array element 'power'
can take values between SI4713_MIN_POWER and SI4713_MAX_POWER. power = 0
is also valid. All the values (0 > power < SI4713_MIN_POWER) are illegal
and hence are all mapped to SI4713_MIN_POWER.

Dinesh Ram 5173332c1e [media] si4713: Modified i2c driver to handle cases where interrupts are not used
Checks have been introduced at several places in the code to test if an
interrupt is set or not. For devices which do not use the interrupt, to
get a valid response, within a specified timeout, the device is polled
instead.
