Hi Artem,
Today's linux-next build (powerpc ppc44x_defconfig) failed like this:
drivers/mtd/ubi/gluebi.c: In function 'gluebi_get_device':
drivers/mtd/ubi/gluebi.c:126: error: implicit declaration of function 'IS_ERR'
drivers/mtd/ubi/gluebi.c:129: error: implicit declaration of function 'PTR_ERR'
Introduced by commit ec5c514efde253de7f28668c88bbae26d2a293de ("UBI: make
gluebi a separate module") from the ubi tree. I guess the conversion
managed to remove an implicit include of linux/err.h.
I have reverted that commit for today. I then needed to also revert
commit 518ceef0c9ca97023e45ae46aedaefa240c690a6 ("UBI: remove built-in
gluebi") to make it build again.

My fault. Will be fixed shortly, thank you!

It is strange that I do not see these errors on my x86_86

Hmm, this means bisection problems, which I'd also like to fix.
But this commit builds just fine for me as well. Would be nice
to see what are the errors.
Any suggestions what I could do to reproduce the build issues?
I'll try at least now to build this on x86 (32-bit).

Did not see compile error on x86 as well. Anyway, I have added more
includes which seem to be missed. Hopefully this problem is fixed
now. Thanks!

Yeah, just did this. Added also linux/mutex.h which we also missed.

however it builds ok on arm too, adding #include <linux/err.h> should
fix this..

The above was a build for a 32 bit powerpc platform. This is an instance
of a general issue when an API is used without explicitly including the
header files that define the API. The needed header file may be included
by some convoluted path that depends on the architecture being built or
even the particular configuration.

Always directly include the header files for APIs you use ...
I see that this particular problem is now fixed, thanks.

Yes, right, those were forgotten.
