[ Upstream commit 323014d85d2699b2879ecb15cd06a15408e3e801 ]

There are several vars unused on this driver, probably because
it was a modified copy of another driver. Get rid of them.

	drivers/edac/sb_edac.c: In function ‘knl_get_dimm_capacity’:
	drivers/edac/sb_edac.c:1343:16: warning: variable ‘sad_size’ set but not used [-Wunused-but-set-variable]
	 1343 |  u64 sad_base, sad_size, sad_limit = 0;
	      |                ^~~~~~~~
	drivers/edac/sb_edac.c: In function ‘sbridge_mce_output_error’:
	drivers/edac/sb_edac.c:2955:8: warning: variable ‘type’ set but not used [-Wunused-but-set-variable]
	 2955 |  char *type, *optype, msg[256];
	      |        ^~~~
	drivers/edac/sb_edac.c: In function ‘sbridge_unregister_mci’:
	drivers/edac/sb_edac.c:3203:22: warning: variable ‘pvt’ set but not used [-Wunused-but-set-variable]
	 3203 |  struct sbridge_pvt *pvt;
	      |                      ^~~
	At top level:
	drivers/edac/sb_edac.c:266:18: warning: ‘correrrthrsld’ defined but not used [-Wunused-const-variable=]
	  266 | static const u32 correrrthrsld[] = {
	      |                  ^~~~~~~~~~~~~
	drivers/edac/sb_edac.c:257:18: warning: ‘correrrcnt’ defined but not used [-Wunused-const-variable=]
	  257 | static const u32 correrrcnt[] = {
	      |                  ^~~~~~~~~~
