This series consists of two small fixes:
1) incorrect max width (and therefore mask calculation) of the prescaler
field in the Global Timer Control Register. The field is actually 8
bit wide according to the Cortex-A9 MPCore Technical Reference Manual
r3p0 [0]
2) non-function: a stray tab which is inconsistent with to the coding
style in the driver
I don't have any ARM/STI hardware to verify the first fix. However, I
tested this on an Amlogic Meson8b board with Cortex-A5 which uses the
same Global Timer implementation as Cortex-A9 SoCs and the documentation
confirms the same register layout: [1]
