[PATCH] soc/fsl/qbman: Use for_each_online_cpu() instead of for_each_cpu()

[PATCH] soc/fsl/qbman: Use for_each_online_cpu() instead of for_each_cpu()

[Fushuai Wang]

Replace the opencoded for_each_cpu(cpu, cpu_online_mask) loop with the
more readable and equivalent for_each_online_cpu(cpu) macro.

Yes. This change makes sense given that for_each_online_cpu expands into the same.

Why not do for the remaining ones too?

linux_tip$ grep -Rw "for_each_cpu" * | grep  cpu_online_mask
arch/riscv/kernel/unaligned_access_speed.c:     for_each_cpu(cpu, cpu_online_mask) {

Rest everyone seems to have moved.

I’m working on updating the remaining instances as well.
To keep the commits clear, I’m sending separate patches for each file/subsystem.
