This series contains straight-forward fixes for different
Versatile Express infrastructure drivers:
- NULL pointer dereference on the error path in the clk driver
- out of boundary array access in the dcscb driver
- broken restart/power off implementation
- mis-interpreted voltage unit in the spc driver

ARM: vexpress/TC2: Convert OPP voltage to uV before storing
power/reset: vexpress: Fix restart/power off operation
arm/mach-vexpress: array accessed out of bounds
clk: vexpress: NULL dereference on error path
Includes an update to 3.15-rc2
