[ Upstream commit 3a3a71f97c30983f1627c2c550d43566e9b634d2 ]
Older compilers warn about initializers with incorrect curly braces:
drivers/gpu/drm/sun4i/sun6i_mipi_dsi.c: In function 'sun6i_dsi_encoder_enable': drivers/gpu/drm/sun4i/sun6i_mipi_dsi.c:720:8: error: missing braces around initializer [-Werror=missing-braces] union phy_configure_opts opts = { 0 }; ^ drivers/gpu/drm/sun4i/sun6i_mipi_dsi.c:720:8: error: (near initialization for 'opts.mipi_dphy') [-Werror=missing-braces]
Use the GNU empty initializer extension to avoid this.
