From: Dan Carpenter <dan.carpenter@linaro.org> stable inclusion from stable-v6.6.92 commit c1d42a239be5c238b7b169a0d84566854a43c2a7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICGAJQ CVE: CVE-2025-38010 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 83c178470e0bf690d34c8c08440f2421b82e881c upstream. We used to take a lock in tegra186_utmi_bias_pad_power_on() but now we have moved the lock into the caller. Unfortunately, when we moved the lock this unlock was left behind and it results in a double unlock. Delete it now.
