Subject: gpio: exar: Set proper output level in exar_direction_output
X-Git-Tag: v4.12-rc1~100^2~72
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=eddeae073760aa3186e2fa0d14a12794687fa786;p=karo-tx-linux.git

gpio: exar: Set proper output level in exar_direction_output

Current code does not set output level in exar_direction_output, fix it.
Also move the direction_output/direction_input code block to avoid forward
declaration for exar_set_value().
