[PATCH] selftests/bpf: Convert comma to semicolon

[PATCH] selftests/bpf: Convert comma to semicolon

[Chen Ni]

Replace comma between expressions with semicolons.

Using a ',' in place of a ';' can have unintended side effects.
Although that is not the case here, it is seems best to use ';'
unless ',' is intended.

Found by inspection.
No functional change intended.
Compile tested only.
