[PATCH] cxl: Include range.h in cxl.h

[PATCH] cxl: Include range.h in cxl.h

[Nathan Chancellor]

After commit aefeb286b960 ("libnvdimm: Don't use "proxy" headers"),
range.h may not be implicitly included, resulting in a build error:

  In file included from drivers/cxl/core/features.c:8:
  drivers/cxl/cxl.h:365:22: error: field 'hpa_range' has incomplete type
    365 |         struct range hpa_range;
        |                      ^~~~~~~~~
  drivers/cxl/cxl.h:562:22: error: field 'hpa_range' has incomplete type
    562 |         struct range hpa_range;
        |                      ^~~~~~~~~
  drivers/cxl/cxl.h:570:22: error: field 'hpa_range' has incomplete type

    803 |         struct range dvsec_range[2];
        |                      ^~~~~~~~~~~

Include range.h in cxl.h explicitly to clear up the errors.

Dave J., I'll pick this up since the nvdimm change was pushed through
libnvdimm.

That said, I'm not seeing this issue.  What config caught this?

Fedora's aarch64 configuration [1] is where I initially noticed this.
Fedora's rpm site seems to be under the weather for me but I have it
mirrored [2] for my own test setup.

Ah, I suspected it was a non-x86 build.

Thanks, I haven't seen issues and 0-day haven't given any (bad) report so far.
