Subject: scsi: dc395x: enabling debug causes build to fail

Hi,
Enabling debug in drivers/scsi/dc395x.c such as the following..
#define DEBUG_MASK DBG_0
..causes the build to fail. This seems to fail pre- linux v6.0, so it's
been broken a very long time.
make drivers/scsi/dc395x.o -j 28 -k
DESCEND objtool
INSTALL libsubcmd_headers

... etc
I stumbled upon this because of a spelling mistake in the following line
in function srb_done():
dprintkdbg(DBG_SG, "srb_done: srb=%p sg=%i(%i/%i) buf=%p\n",
srb, scsi_sg_count(cmd), srb->sg_index, srb->sg_count,
scsi_sgtalbe(cmd));
scsi_sgtalbe should be scsi_sgtable(), and this was introduced into the
driver back in commit:
