fixes asm/unaligned.h related compile errors

[donrudo]

This will fix the compilation errors shown in recent kernel sources caused by the relocation of asm/unaligned.h to its new location at linux/unaligned.h

The change completely slipped past me, thanks for letting me know.

However, these dkms modules can be used with older kernels, so the path needs to be adjusted according to the kernel version.

Also, could you please provide signed-off tags on your patches?

[donrudo]

Oh, thanks for the observation. I added the kernel version validation and signed the commit

EDIT: I just noticed the build is failing. I'll take a look tonight.

The 6.2 errors appear to be related to GCC 13; GitHub Actions have recently switched the default Ubuntu runner to 24.04, and it comes with GCC 13.2.

The issue (clearly) was fixed in later versions, possibly by torvalds/linux@afa4bb7 (although the commit message mentions 32-bit ARM, and a LKML thread linking to it mentions i386).

I think the easiest path forward is just to pin our "stable" build test against something newer. Following the rationale in #57 (comment), we should switch the stable build test to compile against 6.8, which is the kernel version that comes in the latest Ubuntu LTS (24.04). I'll do this now...

thanks! that was quite confusing indeed haha

No need for this and the other comment, on all files.

[jonasmalacofilho]

checkpatch wants the constant operand on the right (on all files).

[donrudo]

hmm I see, applied the change

[jonasmalacofilho]

thanks! that was quite confusing indeed haha

Yeah, especially since the error was in the middle of an output full other other errors, that somehow weren't errors (the build against master also shows most of them). Quite messy... sorry about that.

[jonasmalacofilho]

By the way, the master branch already tests against kernel 6.8, and your next commit should™ no longer hit the workqueue issue with GCC 13.

Thanks!
