Greg Kroah-Hartman	babe59de35	net: dsa: microchip: fix build warning ... In commit 65a9383389db ("net: dsa: microchip: fix initial port flush problem"), the build warning of an unused variable showed up. Fix this by removing the variable entirely.

Tristram Ha	7d807feaa1	net: dsa: microchip: fix initial port flush problem ... [ Upstream commit ad53f5f54f351e967128edbc431f0f26427172cf ] The very first flush in any port will flush all learned addresses in all ports. This can be observed by unplugging the cable from one port while additional ports are connected and dumping the fdb entries. This problem is caused by the initially wrong value programmed to the REG_SW_LUE_CTRL_1 register. Setting SW_FLUSH_STP_TABLE and SW_FLUSH_MSTP_TABLE bits does not have an immediate effect. It is when ksz9477_flush_dyn_mac_table() is called then the SW_FLUSH_STP_TABLE bit takes effect and flushes all learned entries. After that call both bits are reset and so the next port flush will not cause such problem again.
