From 94e19f4fbb1efc21cab860723662b3a9228b428f Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Tue, 7 Mar 2023 13:12:48 +0530 Subject: [PATCH] bus: mhi: ep: Demote unsupported channel error log to debug Not all MHI endpoints will support all available channels. Most of them support only a selected number of channels based on the implementations. In those cases, it is not needed to print error messages in the endpoint. So let's demote the error log to debug.
