3.11.10.9 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Krzysztof Kozlowski <k.kozlow...@samsung.com>
commit a7ab1c8b261305af583ce26bb4a14f555fdaa73e upstream.
During probe the driver allocates dummy I2C device for companion chip
and then allocates a regmap for it. If regmap_init_i2c() fails then the
I2C driver (allocated with i2c_new_dummy()) is not freed and this
resource leaks.
