From: Eugen Hristev <eugen.hristev@xxxxxxxxxxxxx> ld: drivers/media/platform/atmel/atmel-isc-base.o:(.bss+0x0): multiple definition of `debug'; arch/x86/entry/entry_32.o:(.entry.text+0x21ac): first defined here Changed module parameters to static. Reported-by: kbuild test robot <lkp@xxxxxxxxx> Signed-off-by: Eugen Hristev <eugen.hristev@xxxxxxxxxxxxx> --- Hello Hans, Sorry for this, it looks like i386 has a stray weird 'debug' symbol which causes an error. I changed the module parameters of the atmel-isc to 'static' but now they cannot be accessed in the other module files. Will have to create a get function to be used in the other files if needed later. Any other way to make a symbol static to current module and not current file ? It would be useful for other config variables as well. I was not sure if you want to squash this over the faulty patch or add it as a separate patch. If you want me to squash it let me know and I will come up with a squashed new version.
