Subject: [PATCH v3 06/10] drm/msm: Make irq_postinstall optional
Date: Mon,  3 Dec 2018 15:47:19 -0700	[thread overview]
Message-ID: <20181203224723.10450-7-jcrouse@codeaurora.org> (raw)
In-Reply-To: <20181203224723.10450-1-jcrouse-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>

Allow the KMS operation 'irq_postinstall' to be optional
so that the target display drivers don't need to define
a dummy function if they don't need one.

v3: No changes
