From 5e351410667ab0bf0dd1845730cba8b2211781e7 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Mon, 3 Apr 2017 22:50:20 -0700 Subject: net: ibm: emac: remove unused sysrq handler for 'c' key Since commit d6580a9f1523 ("kexec: sysrq: simplify sysrq-c handler"), the sysrq handler for the 'c' key has been sysrq_crash_op. Debugging code in the ibm_emac driver also tries to register a handler for the 'c' key, but this has no effect because register_sysrq_key() doesn't replace existing handlers. Since evidently no one has cared enough to fix this in the last 8 years, and it's very rare for drivers to register sysrq handlers (for good reason), just remove the dead code.
