Subject: [PATCH] ath11k: use MHI provided APIs to allocate and free MHI controller
Date: Mon, 16 Nov 2020 16:01:40 -0800 [thread overview]
Message-ID: <1605571300-4438-1-git-send-email-bbhatt@codeaurora.org> (raw)
Use MHI provided APIs to allocate and free MHI controller to
improve MHI host driver handling. This also fixes a memory leak
as the MHI controller was allocated but never freed.
