Fix unintialized and undefined vars being treated as errors
qseecom: change return value to 0 if app id exists when loading app

Currently qseecom will return the app_id (>0) instead of 0 if the
app id already exists when loading app. Then the userspace client
will release qseecom handle if an non-zero return value is obtained.
Make a change to let qseecom return 0 when app id exist so as to
avoid the incorrect qseecom release.

ARM: 7742/1: topology: export cpu_topology

commit 92bdd3f5eba299b33c2f4407977d6fa2e2a6a0da upstream.

The cpu_topology symbol is required by any driver using the topology
interfaces, which leads to a couple of build errors:

ERROR: "cpu_topology" [drivers/net/ethernet/sfc/sfc.ko] undefined!
ERROR: "cpu_topology" [drivers/cpufreq/arm_big_little.ko] undefined!
ERROR: "cpu_topology" [drivers/block/mtip32xx/mtip32xx.ko] undefined!

The obvious solution is to export this symbol.
