From a9355799343e10014f2acfd4b6844d2335ecafea Mon Sep 17 00:00:00 2001 From: Gongwei Li Date: Fri, 21 Aug 2026 10:45:55 +0800 Subject: [PATCH] Bluetooth: hci_uart: Fix false success return in hci_uart_setup() When reading the local version information for vendor detection fails, the error is only printed and 0 is returned, which masks the setup failure from the HCI core. Return PTR_ERR(skb) instead.
