Subject: bitmap: fix seq_bitmap and seq_cpumask to take const pointer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cb78a0ce69fad2026825f957e24e2d9cda1ec9f1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.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.
