[PATCH 4.20 49/80] gpio: altera-a10sr: Set proper output level for direction_output

[Greg Kroah-Hartman]

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

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

From: Axel Lin <axel....@ingics.com>

commit 2095a45e345e669ea77a9b34bdd7de5ceb422f93 upstream.

The altr_a10sr_gpio_direction_output should set proper output level
based on the value argument.

Fixes: 26a48c4cc2f1 ("gpio: altera-a10sr: Add A10 System Resource Chip GPIO 
support.")
