Hi all,
After merging the drm tree and then some other trees which seem to have
allowed the driver to be built much later in the merge process today's
linux-next build (x86_64 allmodconfig) failed like this:
/tmp/next/build/drivers/gpu/drm/stm/lvds.c:1212:19: error: initialization of 'void (*)(struct platform_device *)' from incompatible pointer type 'int (*)(struct platform_device *)' [-Werror=incompatible-pointer-types]
1212 | .remove = lvds_remove,
| ^~~~~~~~~~~
/tmp/next/build/drivers/gpu/drm/stm/lvds.c:1212:19: note: (near initialization for 'lvds_platform_driver.<anonymous>.remove')
Caused by commit
6597efcfc53585d5 ("drm/stm: Allow build with COMPILE_TEST=y")
interacting with
aca1cbc1c9860e39 ("drm/stm: lvds: add new STM32 LVDS Display Interface Transmitter driver")
0edb555a65d1ef04 ("platform: Make platform_driver::remove() return void")
I have applied the below fixup patch.
