Input: ad7879 - split bus logic out The ad7879 driver is using the old bus method of only supporting one at a time (I2C or SPI). So refactor it like the other input drivers that support multiple busses simultaneously.

Input: ad7879 - convert to use regmap Instead of rolling our own infrastructure to provide uniform access to I2C and SPI buses, let's switch to using regmap.

Input: ad7879 - consolidate PM methods The PM methods are basically the same for SPI and I2C busses, so let's use the same dev_pm_ops for both of them. Acked-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

Input: ad7879 - return plain error code from ad7879_probe() With the switch to devm, there is no need for ad7879_probe() to return the touchscreen structure, we can use plain error code. This also fixes issue introduced with devm concersion, where we returned 0 on success (which worked OK since IS_ERR(0) would not trigger, but was not correct regardless).
