compilation warnings/errors

Hi Hans/Matti

I did a compilation of the media_build tree against Fedora Rawhide, to check what warnings are happening with gcc 4.6, as it is easier to me to just run a VM with Rawhide than to keep an updated set of gcc compiled by me on some place.

The compilation, however, ended earlier due to some errors at TI WL1273 FM driver.

I'm enclosing the warnings and errors when compiling media_build on Fedora rawhide.

Rawhide kernel is 2.6.38-rc7 - 32 bits (probably plus some Fedora patches - in general, backports from the -next tree).

I suspect that this could be due to some platform_data that might be at -next or at -rc7 that are not present on my tree, but it would be great to take a look on it, otherwise I'll may have problems when merging it upstream or submitting it to -next.

Could you please take a look on it?

Thanks!
Mauro.

Hi Hans/Matti

I did a compilation of the media_build tree against Fedora Rawhide, to check what warnings are happening with gcc 4.6, as it is easier to me to just run a VM with Rawhide than to keep an updated set of gcc compiled by me on some place.

The compilation, however, ended earlier due to some errors at TI WL1273 FM driver.

I'm enclosing the warnings and errors when compiling media_build on Fedora rawhide.

Rawhide kernel is 2.6.38-rc7 - 32 bits (probably plus some Fedora patches - in general, backports from the -next tree).

I suspect that this could be due to some platform_data that might be at -next or at -rc7 that are not present on my tree, but it would be great to take a look on it, otherwise I'll may have problems when merging it upstream or submitting it to -next.

radio-wl1273 depends on include/linux/mfd/wl1273-core.h. This header was changed for 2.6.39. Since this header is also used in drivers/mfd I think the best approach is not to build this driver for 2.6.38. The alternative would be to copy the header and drivers/mfd/wl1273-core.c as well and make sure it is configured and compiled. IMHO it's not worth the effort for a platform driver.

Regards,

Hans
