Subject: [PATCH] drivers/ssb/driver_chipcommon_pmu.c: uninitilized warning

warning message
drivers/ssb/driver_chipcommon_pmu.c: In function ssb_pmu_resources_init
drivers/ssb/driver_chipcommon_pmu.c:420:15: warning: updown_tab_size may
be used uninitilized in this function.

updown_tab_size and depend_tab_size may not be set in the bus->chip_id
switch statement, so set to 0 by default to avoid using uninitialized
stack space.
