linux-next: build failure after merge of the drm-misc tree

[Stephen Rothwell]

Hi all,

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

drivers/gpu/drm/panel/panel-newvision-nv3052c.c:478:19: error: initialization of 'void (*)(struct spi_device *)' from incompatible pointer type 'int (*)(struct spi_device *)' [-Werror=incompatible-pointer-types]
  478 |         .remove = nv3052c_remove,
      |                   ^~~~~~~~~~~~~~
drivers/gpu/drm/panel/panel-newvision-nv3052c.c:478:19: note: (near initialization for 'nv3052c_driver.remove')

Caused by commit

  49956b505c53 ("drm/panel: Add panel driver for NewVision NV3052C based LCDs")

interacting with commit

  2cbfa2128662 ("spi: make remove callback a void function")

from Linus' tree (merged in v5.18-rc1).

I applied the following merge resolution patch for today.

From: Stephen Rothwell <sfr at canb.auug.org.au>
Date: Wed, 6 Apr 2022 10:46:57 +1000
Subject: [PATCH] fixup for "spi: make remove callback a void function"
