Subject: [PATCH] bus: mhi: core: Use macros for execution environment features
Date: Mon, 8 Nov 2021 14:19:38 -0800 [thread overview]
Message-ID: <1636409978-31847-1-git-send-email-quic_bbhatt@quicinc.com> (raw)
From: Bhaumik Bhatt <bbhatt@codeaurora.org>
The implementation for execution environment specific functionality
is spread out. Use macros that help determine the paths to be taken.
