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. * tag 'at91-fixes' of git://github.com/at91linux/linux-at91: (257 commits) ARM: at91: drop duplicated config SOC_AT91SAM9 entry ARM: at91/i2c: change id to let i2c-at91 work ARM: at91/i2c: change id to let i2c-gpio work ARM: at91/dts: at91sam9g20ek_common: Fix typos in buttons labels.
