From 53eb703487ca273fc620f737fb561699a4e960d3 Mon Sep 17 00:00:00 2001 From: Nikita Zhandarovich Date: Fri, 12 Jan 2024 05:42:26 -0800 Subject: [PATCH] media: em28xx: annotate unchecked call to media_device_register() [ Upstream commit fd61d77a3d28444b2635f0c8b5a2ecd6a4d94026 ] Static analyzers generate alerts for an unchecked call to `media_device_register()`. However, in this case, the device will work reliably without the media controller API. Add a comment above the call to prevent future unnecessary changes.
