Subject: [PATCH 08/14] iio: triggers: add private data to pollfuncs
Date: Fri, 22 Dec 2017 17:07:15 +0200 [thread overview]
Message-ID: <1513955241-10985-9-git-send-email-eugen.hristev@microchip.com> (raw)
In-Reply-To: <1513955241-10985-1-git-send-email-eugen.hristev@microchip.com>
Add a private data pointer field to pollfunc struct.
This is useful in the trigger handler to get specific data
for the driver registering the pollfunc.
