Subject: [PATCH] usb: typec: ucsi: fix tracepoint related build error
Date: Mon, 9 Apr 2018 09:55:17 +0200 [thread overview]
Message-ID: <20180409075517.15362-1-tobias.regnery@gmail.com> (raw)
The ucsi driver defines several tracepoints, but the header file with the
tracepoint definition trace.h is only conditionally built depending on
CONFIG_FTRACE.
This leads to the following build error with CONFIG_FTRACE=n and
CONFIG_TYPEC_UCSI=m:
ERROR: "__tracepoint_ucsi_command" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_register_port" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_notify" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_reset_ppm" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_run_command" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_ack" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
ERROR: "__tracepoint_ucsi_connector_change" [drivers/usb/typec/ucsi/typec_ucsi.ko] undefined!
With CONFIG_TYPEC_UCSI=y the build fails with several link errors.
Fix this by changing the Makefile to unconditionally build trace.o.
Tracepints are a runtime contruct and no other user of tracepoints depends
on CONFIG_FTRACE.
Fixes: c1b0bc2dabfa ("usb: typec: Add support for UCSI interface")
