Josh Poimboeuf cd80277f65 objtool, media: dib8000: Prevent divide-by-zero in dib8000_set_dds() 
[ Upstream commit e63d465f59 ]

If dib8000_set_dds()'s call to dib8000_read32() returns zero, the result
is a divide-by-zero.  Prevent that from happening.

Fixes the following warning with an UBSAN kernel:

  drivers/media/dvb-frontends/dib8000.o: warning: objtool: dib8000_tune() falls through to next function dib8096p_cfg_DibRx()

Fixes: 173a64cb3f ("[media] dib8000: enhancement")
