[PATCH] perf/x86/intel/uncore: Convert comma to semicolon
Posted by Chen Ni 3 weeks, 4 days ago
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.

We need a "Fixes" tag here.

Thanks for finding and fixing this hidden issue.
