Subject: [PATCH RFT] gpio: exar: Set proper output level in exar_direction_output
Date: Sun, 26 Feb 2017 22:36:58 +0800	[thread overview]
Message-ID: <20170226143658.24036-1-axel.lin@ingics.com> (raw)

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().

Hi Sudip,
I don't have this h/w, so please review and test if this patch works.
thanks,
Axel
