From 53bb8444eab276a9405cefaed4d8351cb6cc4fba Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Thu, 4 Apr 2019 18:16:03 +0200 Subject: [PATCH] parisc: regs_return_value() should return gpr28 commit 45efd871bf0a47648f119d1b41467f70484de5bc upstream. While working on kretprobes for PA-RISC I was wondering while the kprobes sanity test always fails on kretprobes. This is caused by returning gpr20 instead of gpr28.
