[PATCH 03/10] iio: adc: hx711: remove hx711_remove()
From: David Lechner <dlechner@baylibre.com>

Subsystem:
avia hx711 analog digital converter iio driver, iio subsystem and drivers, the rest · Maintainers:
Andreas Klinger, Jonathan Cameron, Linus Torvalds
By using a few more devm_ functions, we can remove the hx711_remove() function in the hx711 driver. platform_set_drvdata() is also removed since there are no more callers of platform_get_drvdata().
