Subject: bitmap: fix seq_bitmap and seq_cpumask to take const pointer
X-Git-Tag: firefly_0821_release~16421^2~11^2~43
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=cb78a0ce69fad2026825f957e24e2d9cda1ec9f1;p=firefly-linux-kernel-4.4.55.git

bitmap: fix seq_bitmap and seq_cpumask to take const pointer

Impact: cleanup

seq_bitmap just calls bitmap_scnprintf on the bits: that arg can be const.
Similarly, seq_cpumask just calls seq_bitmap.
