6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Spoorthy S <spoorts2@xxxxxxxxxx>
[ Upstream commit 1bb17b4c6c91ad4d9468247cf5f5464fa6440668 ]
Running shellcheck -S on test_arm_calligraph_fp throws warnings SC2086 and SC3049,
$shellcheck -S warning tests/shell/test_arm_callgraph_fp.sh
rm -f $PERF_DATA
: Double quote to prevent globbing and word splitting.
trap cleanup_files exit term int
: In POSIX sh, using lower/mixed case for signal names is undefined.
After fixing the warnings,
$shellcheck tests/shell/test_arm_callgraph_fp.sh
$ echo $?
0
To address the POSIX shell warnings added changes to convert Lowercase
signal names to uppercase in the script and double quoted the
command substitutions($fix to "$fix") to solve Globbing warnings.
