From: Anushree Mathur <anushree.mat...@linux.vnet.ibm.com> Fixed the following shellcheck issues in test_arm_coresight.sh file:
In tools/perf/tests/shell/test_arm_coresight.sh line 31: trap - exit term int ^--^ SC2039: In POSIX sh, using lower/mixed case for signal names is undefined. ^--^ SC2039: In POSIX sh, using lower/mixed case for signal names is undefined. ^-^ SC2039: In POSIX sh, using lower/mixed case for signal names is undefined. In tools/perf/tests/shell/test_arm_coresight.sh line 35: trap cleanup_files exit term int ^--^ SC2039: In POSIX sh, using lower/mixed case for signal names is undefined. ^--^ SC2039: In POSIX sh, using lower/mixed case for signal names is undefined. ^-^ SC2039: In POSIX sh, using lower/mixed case for signal names is undefined. In tools/perf/tests/shell/test_arm_coresight.sh line 92: if [ $? -eq 0 -a -e "$1/enable_sink" ]; then ^-- SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined. Fixed above warnings by: 1)Capitalize signals(INT, TERM, EXIT) to avoid mixed/lower case naming of signals. 2)Expression [p -a q] was not defined,changed it to [p] && [q] to avoid the ambiguity as this is older format using -a or -o ,now we use [p] && [q] in place of [p -a q] and [p] || [q] in place of [p -o q].
