[patch] sata_mv: silence an uninitialized variable warning

From: Dan Carpenter
Date: Sat Mar 10 2012 - 04:00:25 EST


Gcc version 4.6.2-12 complains that if we can't find the "nr-ports"
property in of_property_read_u32_array() then "n_ports" is used
uninitialized. Let's set it to zero in that case.
