Hi all,

After merging the scsi-mkp tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

drivers/scsi/sg.c: In function 'sg_find_srp_by_id':
drivers/scsi/sg.c:2908:4: error: expected '}' before 'else'

Caused by commit

  7323ad3618b6 ("scsi: sg: Replace rq array with xarray")

SG_LOG() degenerates to "{}" in some configs ...

I have used the scsi-mkp tree from next-20210122 for today.
