Subject[PATCH 6/7] EDAC: sb_edac: get rid of unused vars
Date
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[] = {
| ^~~~~~~~~~
