Subject: [PATCH] drm/tegra: fix compile w/ CONFIG_DYNAMIC_DEBUG
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

With CONFIG_DYNAMIC_DEBUG=y, the following compile error occurs:

drivers/gpu/drm/tegra/mipi-phy.c: In function ‘mipi_dphy_timing_validate’:
drivers/gpu/drm/tegra/mipi-phy.c:69:11: error: ‘EINVAL’ undeclared (first use in this function)
drivers/gpu/drm/tegra/mipi-phy.c:69:11: note: each undeclared identifier is reported only once for each function it appears in

Fix this by directly including the header that defines EINVAL.

Fixes: dec727399a4b ("drm/tegra: Add DSI support")
