Hi Jean, After merging the i2c tree, today's linux-next build (powerpc ppc64_defconfig) produced warnings like this: In file included from include/linux/bitops.h:17, from include/linux/kernel.h:15, from drivers/i2c/i2c-boardinfo.c:19: arch/powerpc/include/asm/bitops.h:226: warning: declaration of 'ffs' shadows a built-in function The x86_64 allmodconfig produces similar: In file included from include/linux/bitops.h:17, from include/linux/kernel.h:15, from next/drivers/i2c/i2c-boardinfo.c:19: arch/x86/include/asm/bitops.h:395: warning: declaration of 'ffs' shadows a built-in function Exposed by commit fa4f62e9f3a85490aebe8857e2208c37da851ce3 ("i2c: Build core and algo drivers with -Wshadow"). Jean, I realise that these warnings are not something your tree has added, just that you have exposed them. They are a bit annoying, though. I am using gcc v4.4.3. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
