Subject: perf hists browser: Cleanup hist_browser__fprintf_hierarchy_entry()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=325a62834e81452d2a6e253444022cf493bbabfc;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

perf hists browser: Cleanup hist_browser__fprintf_hierarchy_entry()

The hist_browser__fprintf_hierarchy_entry() if to dump current output
into a file so it needs to be sync-ed with the corresponding function
hist_browser__show_hierarchy_entry().  So use hists->nr_hpp_node to
indent width and use first fmt_node to print overhead columns instead of
checking whether it's a sort entry (or dynamic entry).
