stable inclusion from stable-v5.10.211 commit 70d92abbe29692a3de8697ae082c60f2d21ab482 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2O0 CVE: CVE-2024-26751
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
Without the terminator, if a con_id is passed to gpio_find() that does not exist in the lookup table the function will not stop looping correctly, and eventually cause an oops.
