Subject: [RESEND PATCH] ath11k: use MHI provided APIs to allocate and free MHI controller
Date: Tue, 17 Nov 2020 09:33:56 -0800	[thread overview]
Message-ID: <1605634436-36506-1-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.
