Hi all,
This small series makes cosmetic style cleanups in the arm64 kselftests to improve readability and suppress checkpatch warnings. These changes are purely cosmetic and do not affect functionality.
Changes in this series: * Suppress unnecessary checkpatch warning in a comment * Add parentheses around sizeof for clarity * Remove redundant blank line

Remove an unnecessary blank line to improve code style consistency.
``` [command] ./scripts/checkpatch.pl --strict -f <path/to/file>
[output] CHECK: Please don't use multiple blank lines CHECK: Blank lines aren't necessary before a close brace '}' ```

The comment was correct, but `checkpatch` script flagged it with a warning as shown in the output section. The comment is slightly modified to improve readability, which also suppresses the warning.
``` [command] ./script/checkpatch.pl --strict -f tools/testing/selftests/arm64/fp/fp-stress.c
[output] WARNING: Possible repeated word: 'on' ```
Fixes: 98102a2cb7860 : kselftest/arm64: Hold fp-stress children until they're all spawned.

Added parentheses around sizeof to make the expression clearer and improve readability. This change has no functional impact.
``` [command] ./scripts/checkpatch.pl tools/testing/selftests/arm64/fp/sve-ptrace.c
[output] WARNING: sizeof *sve should be sizeof(*sve) ```

Applied to arm64 (for-next/selftests), thanks!
