Subject: [PATCH] perf cs-etm: Move defined of traceid_list
Date: Tue,  5 May 2020 21:36:42 +0800
Message-ID: <20200505133642.4756-1-leo.yan@linaro.org> (raw)

The variable 'traceid_list' is defined in the header file cs-etm.h,
if multiple C files include cs-etm.h the compiler might complaint for
multiple definition of 'traceid_list'.

To fix multiple definition error, move the definition of 'traceid_list'
into cs-etm.c.

Fixes: cd8bfd8c973e ("perf tools: Add processing of coresight metadata")
