Josh Poimboeuf b9249da6b0 objtool, media: dib8000: Prevent divide-by-zero in dib8000_set_dds() ... [ Upstream commit e63d465f59011dede0a0f1d21718b59a64c3ff5c ] 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") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Josh Poimboeuf <jpoimboe@kernel.org> Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: Mauro Carvalho Chehab <mchehab@kernel.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Link: https://lore.kernel.org/r/bd1d504d930ae3f073b1e071bcf62cae7708773c.1742852847.git.jpoimboe@kernel.org Closes: https://lore.kernel.org/r/202503210602.fvH5DO1i-lkp@intel.com/ Signed-off-by: Sasha Levin <sashal@kernel.org>		2025-04-10 14:33:37 +02:00
