Subject: [PATCH 4.11 20/36] pinctrl: stm32: Fix bad function call

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

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

From: Alexandre TORGUE <alexandre.torgue@...com>

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")
