Why unsigned long? It's for the registers value, wouldn't u32 fit better?

How about using a sentinel at the array end and getting rid of the global
'exynos4_pmu_entry_cnt' variable? For instance an empty entry { } ?

"EXYNOS4210 PMU initialized\n", "EXYNOS4210 PMU initialization completed\n" ?
Moreover AFAIK pr_info is preferred.

Why unsigned long? It's for the registers value, wouldn't u32 fit better?

How about using a sentinel at the array end and getting rid of the global
'exynos4_pmu_entry_cnt' variable? For instance an empty entry { } ?

"EXYNOS4210 PMU initialized\n", "EXYNOS4210 PMU initialization completed\n" ?
Moreover AFAIK pr_info is preferred.
