When using mxs-auart based console, sometime we need the sysrq function to help debugging kernel. The sysrq code is basically there, this patch just simply enable it. Signed-off-by: Janusz Uzycki <j.uzycki@elproma.com.pl> --- Changes from v1 (the initial version of the patch): * the patch was extracted as indendent from my previous patchset "serial: mxs-auart: use mctrl_gpio helpers for handling modem signals (v2.2c)" "[PATCH 4/4] serial: mxs-auart: add sysrq support" * removed obvious comment about required order of SUPPORT_SYSRQ define and serial_core.h include The patch is resent as ready to apply. I resend it again because last time in conver letter I swapped subject with in-reply-to and the patch could be omited. This time I've added versioning and changelog. --- drivers/tty/serial/mxs-auart.c | 4 ++++ 1 file changed, 4 insertions(+)
