[PATCH 4.9 24/41] pinctrl: stm32: Fix bad function call

From: Greg Kroah-Hartman
Date: Mon Jul 10 2017 - 13:13:56 EST


4.9-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alexandre TORGUE <alexandre.torgue@xxxxxx>

commit b7c747d4627462f25b3daabf49c18895a6722faa upstream.

In stm32_pconf_parse_conf function, stm32_pmx_gpio_set_direction is
called with wrong parameter value. Indeed, using NULL value for range
will raise an oops.

Fixes: aceb16dc2da5 ("pinctrl: Add STM32 MCUs support")
