There are three checkpatch issues to be handled here:
WARNING: function definition argument 'int' should also have an identifier name
#764: FILE: drivers/media/pci/ddbridge/ddbridge-mci.h:147:
+struct dvb_frontend
WARNING: function definition argument 'struct dvb_frontend *' should also have
an identifier name
#764: FILE: drivers/media/pci/ddbridge/ddbridge-mci.h:147:
+struct dvb_frontend
WARNING: function definition argument 'int' should also have an identifier name
#764: FILE: drivers/media/pci/ddbridge/ddbridge-mci.h:147:
+struct dvb_frontend
Please submit a patch later addressing it.
