Subject: perf: intel-tpebs: Fix incorrect usage of zfree()
X-Git-Tag: block-6.15-20250403~13^2~34
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=6d2dcd635204c023eb5328ad7d38b198a5558c9b;p=linux-block.git

perf: intel-tpebs: Fix incorrect usage of zfree()

zfree() requires an address otherwise it frees what's in name, rather
than name itself. Pass the address of name to fix it.

This was the only incorrect occurrence in Perf found using a search.

Fixes: 8db5cabcf1b6 ("perf stat: Fork and launch 'perf record' when 'perf stat' needs to get retire latency value for a metric.")
