Subject: staging/8821ae driver breaks allyes build in 3.16-rc*


Hi,

I cannot build make allyesconfig in current Linus mainline, because
drivers/staging/rtl8821ae has a lot of compile errors.

I tried to fix some, but it seems to be wide spread and sometimes
non obvious.

It may be related to the following series from Sachin,
however when just reverting those the driver gains some new
unrelated compile errors. It may be still a good idea
to revert those because the earlier errors are likely
easier to fix. Or just disable the driver until it at least
builds.

Please fix it in some way, allyesconfig should build!

allyesconfig should turn off the staging drivers, how did you turn it
on?

It builds here for me, or at least I thought it did, let me go check...

Ok, that's odd, I thought we didn't build staging drivers for
allyesconfig, but you are right, we do.

allyesconfig builds the staging directory just fine for me here, with
Linus's current tree:

$ git branch
* master d057190925d9 Merge branch 'locking-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip


And gcc version:
$ gcc --version | head -n 1
gcc (GCC) 4.9.0 20140604 (prerelease)


Are you sure your tree is "clean" at the moment?

thanks,

It was changed a few kernels ago iirc.

Ok I builds after I threw the old build directory away. Mysterious.

Sorry for the false alarm.
