Hi all,

After merging the driver-core tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/media/platform/raspberrypi/pisp_be/pisp_be.c:1786:27: error: initialization of 'void (*)(struct platform_device *)' from incompatible pointer type 'int (*)(struct platform_device *)' [-Werror=incompatible-pointer-types]
 1786 |         .remove         = pispbe_remove,
      |                           ^~~~~~~~~~~~~
drivers/media/platform/raspberrypi/pisp_be/pisp_be.c:1786:27: note: (near initialization for 'pispbe_pdrv.<anonymous>.remove')
cc1: all warnings being treated as errors

Caused by commit

  0edb555a65d1 ("platform: Make platform_driver::remove() return void")

interacting withc commit

  12187bd5d4f8 ("media: raspberrypi: Add support for PiSP BE")

from the vl4-dvb-next tree.

I have applied the following fix up patch.
