Subject: [PATCH v3] bus: mhi: core: Return EAGAIN if MHI ring is full
Date: Wed, 17 Feb 2021 09:26:49 -0700 [thread overview]
Message-ID: <1613579209-3675-1-git-send-email-jhugo@codeaurora.org> (raw)
From: Fan Wu <wufan@codeaurora.org>
Currently ENOMEM is returned when MHI ring is full. This error code is
very misleading. Change to EAGAIN instead.
