From b015ba29ca09b0e3750b4de365d3baf9c5b11450 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 2 May 2013 08:29:43 -0300 Subject: [PATCH] [media] media: i2c: Convert to devm_gpio_request_one() Using the managed function the gpio_free() calls can be removed from the probe error path and the remove handler.
