From 854901ccd43a2f547d2bf090456214c6033144c5 Mon Sep 17 00:00:00 2001 From: Wolfgang Wallner Date: Fri, 24 Oct 2025 14:52:45 +0200 Subject: [PATCH] gpio: Return -ENODEV if gpio_hog_lookup_name() is empty If CONFIG_GPIO_HOG is not set, then gpio_hog_lookup_name() is empty, and thus does not initialize any of its parameters. It does still return 0 though, and so any calling function might assume that the parameters have been initialized successfully. Change the return value to -ENODEV in this case, as the function would in the case when CONFIG_GPIO_HOG is set but the gpio hog could not be found.
