This breaks compilation:
arch/arm/mach-at91/at91sam926x_time.c: In function 'clocksource_init':
arch/arm/mach-at91/at91sam926x_time.c:57:3: error: 'ret' undeclared (first use in this function)
arch/arm/mach-at91/at91sam926x_time.c:57:3: note: each undeclared identifier is reported only once for each function it appears in
arch/arm/mach-at91/at91sam926x_time.c:58:3: error: 'dev' undeclared (first use in this function)
I guess the patch order is wrong.
