mv88e6xxx: Fix uninitialized variable warning.
In mv88e6xxx_probe(), ("np" or "pdata") might be an invariant
but GCC can't see that, therefore:
drivers/net/dsa/mv88e6xxx/chip.c: In function ‘mv88e6xxx_probe’:
drivers/net/dsa/mv88e6xxx/chip.c:4420:13: warning: ‘compat_info’ may be used uninitialized in this function [-Wmaybe-uninitialized]
chip->info = compat_info;
Actually, it should have warned on the "if (!compat_info)" test, but
whatever.
Explicitly initialize to NULL in the variable declaration to
deal with this.
