When I used static checker Smatch for perf building, the main target is to check if there have any potential issues in Arm cs-etm code. So finally I get many reporting for errors/warnings.
I used below command for using static checker with perf building:
# make VF=1 CORESIGHT=1 -C tools/perf/ \ CHECK="/root/Work/smatch/smatch --full-path" \ CC=/root/Work/smatch/cgcc | tee smatch_reports.txt
I reviewed the errors one by one, if I understood some of these errors so changed the code as I can, this patch set is the working result; but still leave some errors due to I don't know what's the best way to fix it. There also have many inconsistent indenting warnings. So I firstly send out this patch set and let's see what's the feedback from public reviewing.
