Subject[PATCH -next] ocelot: remove unused variable 'rc' in vcap_cmd()
Date
Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/ethernet/mscc/ocelot_ace.c: In function ‘vcap_cmd’:
drivers/net/ethernet/mscc/ocelot_ace.c:108:6: warning: variable ‘rc’ set
but not used [-Wunused-but-set-variable]
int rc;
^
It's never used since introduction in commit b596229448dd ("net: mscc:
ocelot: Add support for tcam")
