| Subject: regmap: Fix memory leak from regmap_register_patch |
| |
| From: Charles Keepax <ckeepax@opensource.cirrus.com> |
| |
| [ Upstream commit 95b2c3ec4cb1689db2389c251d39f64490ba641c ] |
| |
| When a register patch is registered the reg_sequence is copied but the |
| memory allocated is never freed. Add a kfree in regmap_exit to clean it |
| up. |
| |
| Fixes: 22f0d90a3482 ("regmap: Support register patch sets") |
