Merge tag 'vexpress/fixes-for-3.15' of git://git.linaro.org/people/pawel.moll/linux into fixes
ARM Versatile Express fixes for 3.15
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
* tag 'vexpress/fixes-for-3.15' of git://git.linaro.org/people/pawel.moll/linux:
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
