Subject: [PATCH 5.6 022/194] sun6i: dsi: fix gcc-4.8

From: Arnd Bergmann <arnd@...db.de>

[ 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.

Fixes: bb3b6fcb6849 ("sun6i: dsi: Convert to generic phy handling")
