perf/x86/intel/uncore: Remove extra double quote mark
The third argument in INTEL_UNCORE_FR_EVENT_DESC() is subject to __stringify(), and the extra double quote marks can result in the expansion "3.814697266e-6" in the sysfs knobs, instead of 3.814697266e-6. This is incorrect, though it may still work for perf, e.g. perf stat -e uncore_iio_free_running_0/bw_in_port0/ Fixes: d898704 ("perf/x86/intel/uncore: Support IIO free-running counters on DMR") Closes: https://lore.kernel.org/all/20251231224233.113839-1-zide.chen@intel.com/ Reported-by: Chun-Tse Shao <ctshao@google.com> Signed-off-by: Zide Chen <zide.chen@intel.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Reviewed-by: Chun-Tse Shao <ctshao@google.com> Reviewed-by: Dapeng Mi <dapeng1.mi@linux.intel.com> Link: https://patch.msgid.link/20260313174050.171704-5-zide.chen@intel.com
