It sounds that earlier versions of GCC have troubles when doing const math at compile time, if no typecast is used: on i386: ERROR: modpost: "__floatunsidf" [drivers/media/pci/ttpci/dvb-ttpci.ko] undefined! ERROR: modpost: "__ltdf2" [drivers/media/pci/ttpci/dvb-ttpci.ko] undefined! The warning was generated on gcc (SUSE Linux) 7.5.0. Gcc 9.2 compiles it fine. As an added bonus, it also fixes this objtool warning: drivers/media/pci/ttpci/av7110_v4l.c:163:11: error: SSE register return with SSE disabled Reported-by: Randy Dunlap <rdunlap@infradead.org> Acked-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
