Merge tag 'at91-fixes' of git://github.com/at91linux/linux-at91 into fixes
From Nicolas Ferre <nicolas.ferre@atmel.com>:
A mix of typos and critical fixes.
The most important ones are a duplicated definition of a Kconfig
variable and the handling of external interrupts for non-DT case.
The new at91sam9g10 was suffering a recognition issue due to an ID
mis-interpreted: this was leading to a kernel panic.
