Subject: [PATCH v2 1/3] perf vendor events: Syntax corrections in Neoverse N1 json
There are some syntactical mistakes in the json files for the Cortex A76
N1 (Neoverse N1). This was obstructing parsing from an external tool.
This patch fixes the erroneous placement of commas causing the problems.
Signed-off-by: Andrew Kilroy <andrew.kilroy@....com>
