Subject: [PATCH] drm/sun4i: Fix uninitialized variables in vi layer
Date: Wed,  6 Dec 2017 16:26:03 +0100	[thread overview]
Message-ID: <20171206152603.25937-1-jernej.skrabec@siol.net> (raw)

min_scale and max_scale in sun8i_vi_layer_atomic_check() can be used
without initialization.

Fix that.

Fixes: 	b862a648de3b (drm/sun4i: Add support for HW scaling to DE2)
