[PATCH 5.8 017/124] Platform: OLPC: Fix memleak in olpc_ec_probe

[Greg Kroah-Hartman]

From: Dinghao Liu <dinghao....@zju.edu.cn>

commit 4fd9ac6bd3044734a7028bd993944c3617d1eede upstream.

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")
