There is a recent discussion at KS ML with regards to use W=1 as default.

No idea if this will happen or not, but it doesn't hurt cleaning up W=1
warnings from the EDAC subsystem, specially since it helps to cleanup
a few things.

This patch series addresses most of such warnings.  After this series,
there will be just two W=1 warnings:

1) i5100 EDAC driver:

	drivers/edac/i5100_edac.c: In function ‘i5100_read_log’:
	drivers/edac/i5100_edac.c:487:11: warning: variable ‘ecc_loc’ set but not used [-Wunused-but-set-variable]
	  487 |  unsigned ecc_loc = 0;
	      |           ^~~~~~~


   The ecc_loc contents is filled from MC data, but it is not used anywere.
   The i5100 MC is very old: the affected code was added in 2008. It should
   probably be safe to just drop the corresponding data, but, as it may
   contain some relevant info, I was a little reticent of doing that.

2) Xgene EDAC driver:

	drivers/edac/xgene_edac.c: In function ‘xgene_edac_rb_report’:
	drivers/edac/xgene_edac.c:1486:7: warning: variable ‘address’ set but not used [-Wunused-but-set-variable]
	 1486 |   u32 address;
	      |       ^~~~~~~

   I suspect that the content of the address field should actually be used on
   at least some of the logs.

I may eventually submit patches later to address the above cases, but let's
solve first the other cases, as they all sound trivial enough.

Mauro Carvalho Chehab (7):
  EDAC: i5100_edac: get rid of an unused var
  EDAC: i7300_edac: rename a kernel-doc var description
  EDAC: i7300_edac: fix a kernel-doc syntax

  EDAC: i5400_edac: get rid of some unused vars
  EDAC: sb_edac: get rid of unused vars
  EDAC: skx_common: get rid of unused type var

+ Khuong Dinh <khuong@os.amperecomputing.com> for that.

Looks ok to me at a quick glance, ACK.

I've already sent the 5.4 pull request to Linus so you could queue those
after -rc1. It's not like they're urgent or so.

Thx.

Me too. Also ACK.

Yeah, that's my plan.

Thanks,
