Geert Uytterhoeven 50262c8533 net: stmmac: sti: Fix uninitialized pointer dereference if !OF
If CONFIG_OF is not set:

drivers/net/ethernet/stmicro/stmmac/dwmac-sti.c: In function ‘sti_dwmac_parse_data’:
drivers/net/ethernet/stmicro/stmmac/dwmac-sti.c:318: warning: ‘rs’ is used uninitialized in this function

of_property_read_string() will return -ENOSYS in this case, and rs will
be an uninitialized pointer.

While the fallback clock selection is already selected correctly in this
case, the string comparisons should be skipped too, else the system will
crash while dereferencing the uninitialized pointer.
