Subject: [PATCH] video: exynos: fix modular build
Date: Tue, 19 May 2015 12:17:23 +0000 [thread overview]
Message-ID: <2708563.ADEZz3igC5@wuerfel> (raw)
The s6e8ax0 driver has a dependency on BACKLIGHT_CLASS_DEVICE,
which can be configured as a loadable module, so we have to
make the driver a tristate symbol as well, to avoid this error:
drivers/built-in.o: In function `s6e8ax0_probe':
:(.text+0x23a48): undefined reference to `devm_backlight_device_register'
This also means we get another error from a missing export, which
this fixes as well:
ERROR: "exynos_mipi_dsi_register_lcd_driver" [drivers/video/fbdev/exynos/s6e8ax0.ko] undefined!
Finally, the EXYNOS_VIDEO option is turned into tristate as well
for good measure, as all framebuffer drivers should be configurable
as modules.
