fae2b89a (ARM: l2x0: add empty l2x0_of_init) adds a static inline function that returns -ENODEV, but at least on tegra cache-l2x0.h is included without errno.h being pulled in first, resulting in compile errors if OF isn't enabled: In file included from arch/arm/mach-tegra/common.c:26: arch/arm/include/asm/hardware/cache-l2x0.h: In function 'l2x0_of_init': arch/arm/include/asm/hardware/cache-l2x0.h:110: error: 'ENODEV' undeclared (first use in this function) arch/arm/include/asm/hardware/cache-l2x0.h:110: error: (Each undeclared identifier is reported only once arch/arm/include/asm/hardware/cache-l2x0.h:110: error: for each function it appears in.) Add errno.h to the include file to make it self-contained. Signed-off-by:
