Subject: rxrpc: Fix trace string
X-Git-Tag: v4.14.189~1
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=98f593aeade9298bcd44baa79f197716c515b1bf;p=users%2Fdwmw2%2Flinux.git

rxrpc: Fix trace string

commit aadf9dcef9d4cd68c73a4ab934f93319c4becc47 upstream.

The trace symbol printer (__print_symbolic()) ignores symbols that map to
an empty string and prints the hex value instead.

Fix the symbol for rxrpc_cong_no_change to " -" instead of "" to avoid
this.

Fixes: b54a134a7de4 ("rxrpc: Fix handling of enums-to-string translation in tracing")
