From ad38cc5f6d4f2c74ed69e2c017691e428549b2bd Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Tue, 15 Sep 2015 16:12:33 +0300 Subject: [PATCH] fbdev: omap2: connector-dvi: use of_get_i2c_adapter_by_node interface This change is needed to properly lock I2C bus driver, which serves DDC. Prior to this change i2c_put_adapter() is misused, which may lead to an overflow over zero of I2C bus driver user counter.
