[PATCH 4.14 021/343] drm/sun4i: hdmi: Fix double flag assignation

[Greg Kroah-Hartman]

From: Maxime Ripard <maxime.ripard@xxxxxxxxxxx>

[ Upstream commit 1e0ff648940e603cab6c52cf3723017d30d78f30 ]

The is_double flag is a boolean currently assigned to the value of the d
variable, that is either 1 or 2. It means that this is_double variable is
always set to true, even though the initial intent was to have it set to
true when d is 2.

Fix this.
