Subject: drm/tegra: fix compile w/ CONFIG_DYNAMIC_DEBUG
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=81239c6f7972d4909a6862d08ed1d2943983ffd4;p=openwrt%2Fstaging%2Fblogic.git

drm/tegra: fix compile w/ CONFIG_DYNAMIC_DEBUG

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.
