Adding these to the end of variable makes it take multiple lines as we need to break after 80 columns. And both the styles are already mixed in existing file. So, would fix it separately in case I go for it :) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Drivers supporting multiple clusters or multiple 'struct cpufreq_policy' instances may need to keep per-policy data. If the core doesn't support them, they might do it in the most unoptimized way: 'per-cpu' data. This patch adds another field in 'struct cpufreq_policy': 'driver_data'. It isn't accessed by core and is for driver's internal use. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> --- include/linux/cpufreq.h | 3 +++ 1 file changed, 3 insertions(+)
