Platform: OLPC: Fix memleak in olpc_ec_probe
When devm_regulator_register() fails, ec should be freed just like when olpc_ec_cmd() fails. Fixes: 231c0c216172a ("Platform: OLPC: Add a regulator for the DCON") Signed-off-by: Dinghao Liu <dinghao.liu@zju.edu.cn> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
