Subject: of/i2c: call i2c_verify_client from of_find_i2c_device_by_node
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d9afca37dea077d11ed67fc7f93b95c003e58819;p=deliverable%2Flinux.git

of/i2c: call i2c_verify_client from of_find_i2c_device_by_node

i2c_bus_type may contain both I2C clients and I2C adapters. Fix
of_find_i2c_device_by_node to call i2c_verify_client to ensure that it
only returns non-NULL of I2C clients.
