Subject: linux-next: build failure after merge of the net-next tree

Hi all,

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

drivers/net/wwan/mhi_wwan_mbim.c: In function 'mhi_mbim_probe':
drivers/net/wwan/mhi_wwan_mbim.c:612:8: error: too many arguments to function 'mhi_prepare_for_transfer'
  612 |  err = mhi_prepare_for_transfer(mhi_dev, 0);
      |        ^~~~~~~~~~~~~~~~~~~~~~~~
In file included from drivers/net/wwan/mhi_wwan_mbim.c:18:
include/linux/mhi.h:725:5: note: declared here
  725 | int mhi_prepare_for_transfer(struct mhi_device *mhi_dev);
      |     ^~~~~~~~~~~~~~~~~~~~~~~~

Caused by commits

  aa730a9905b7 ("net: wwan: Add MHI MBIM network driver")
  ab996c420508 ("wwan: mhi: Fix build.")
  a85b99ab6abb ("Revert "wwan: mhi: Fix build."")
