Subject: [PATCH 08/63] perf cs-etm: Fix definition of macro TO_CS_QUEUE_NR
Date: Thu,  7 Nov 2019 15:59:16 -0300	[thread overview]
Message-ID: <20191107190011.23924-9-acme@kernel.org> (raw)
In-Reply-To: <20191107190011.23924-1-acme@kernel.org>

From: Leo Yan <leo.yan@linaro•org>

Macro TO_CS_QUEUE_NR definition has a typo, which uses 'trace_id_chan'
as its parameter, this doesn't match with its definition body which uses
'trace_chan_id'.  So renames the parameter to 'trace_chan_id'.

It's luck to have a local variable 'trace_chan_id' in the function
cs_etm__setup_queue(), even we wrongly define the macro TO_CS_QUEUE_NR,
the local variable 'trace_chan_id' is used rather than the macro's
parameter 'trace_id_chan'; so the compiler doesn't complain for this
before.

After renaming the parameter, it leads to a compiling error due
cs_etm__setup_queue() has no variable 'trace_id_chan'.  This patch uses
the variable 'trace_chan_id' for the macro so that fixes the compiling
error.
