Every tracing file must have its own TRACE_SYSTEM defined.
The brcmsmac tracepoint header broke this and added in the middle
of the file:
#undef TRACE_SYSTEM
#define TRACE_SYSTEM brcmsmac
#undef TRACE_SYSTEM
#define TRACE_SYSTEM brcmsmac_tx
#undef TRACE_SYSTEM
#define TRACE_SYSTEM brcmsmac_msg
Unfortunately, this broke new code in the ftrace infrastructure.
Moving each of these TRACE_SYSTEMs into their own trace file with
just one TRACE_SYSTEM per file fixes the issue.

Add the brcmsmac_tx trace system for tx debugging. Existing code to dump
tx status and descriptors are converted to using tracepoints, allowing
for more efficient collection and post-processing of this data. These
tracepoints are placed to collect data for all tx frames instead of only
on errors. Logging of tx errors is also improved.

Add a new brcmsmac_msg trace system to enable writing of debug messages
to the trace buffer, and add brcms_* macros for storing device debug
messages in the trace buffer in addition to the printk log buffer.

Since the runtime overhead of trace support is small when tracing is
disabled, users may be interested in turning on trace support while
leaving other debug features off. Add a new config option named
CONFIG_BRCM_TRACING for this purpose.

Add the brcm80211 tree to drivers/net/wireless, and disable the version that's
in drivers/staging. This version includes the sources currently in staging,
plus any changes that have been sent out for review.
Sources in staging will be deleted in a followup patch.
