Subject: [PATCH] regulator: bq257xx: Fix device node reference leak in bq257xx_reg_dt_parse_gpio()
Date: Tue, 24 Feb 2026 19:19:03 +0800	[thread overview]
Message-ID: <20260224-bq257-v1-1-8ebbc731c1c3@gmail.com> (raw)

In bq257xx_reg_dt_parse_gpio(), if fails to get subchild, it returns
without calling of_node_put(child), causing the device node reference
leak.

Fixes: 981dd162b635 ("regulator: bq257xx: Add bq257xx boost regulator driver")
