From 42c4668f7efe1485dfc382517b412c0c6ab102b8 Mon Sep 17 00:00:00 2001 From: Bhaumik Bhatt quic_bbhatt@quicinc.com Date: Thu, 16 Dec 2021 13:42:23 +0530 Subject: [PATCH] bus: mhi: core: Fix reading wake_capable channel configuration
The 'wake-capable' entry in channel configuration is not set when parsing the configuration specified by the controller driver. Add the missing entry to ensure channel is correctly specified as a 'wake-capable' channel.
