From 22766ed8a235f3c9043678c7c594afe683b2372f Mon Sep 17 00:00:00 2001 From: Daniel Thompson Date: Fri, 28 Mar 2014 11:41:38 +0000 Subject: [PATCH] serial: mux: Align SUPPORT_SYSRQ behaviour with other drivers. The mux driver is anomalous among all the serial drivers that can define SUPPORT_SYSRQ because it can, with some configs, set SUPPORT_SYSRQ when SERIAL_CORE_CONSOLE is not set. Not only does this impose a pointless (but tiny) runtime overhead for such configs but, more significantly, it adds needless complexity when doing a code review to check for unexpected side effects of any changes to the serial core. This is (cross-)compile tested only because I do not have any PA-RISC hardware.
