Subject: linux-next: manual merge of the scsi-mkp tree with Linus' tree

Hi all,

Today's linux-next merge of the scsi-mkp tree got a conflict in:

  drivers/scsi/ufs/ufshcd.c

between commit:

  88b099006d83 ("scsi: ufs: core: Revert "scsi: ufs: Synchronize SCSI and UFS error handling"")

from Linus' tree and commit:

  87bf6a6bbe8b ("scsi: ufs: core: Do not exit ufshcd_err_handler() unless operational or dead")

from the scsi-mkp tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

-- 
Cheers,
Stephen Rothwell
