    rtlwifi: rtl8192ce: Remove false positives for kmemleak · f11bbfd8
    Larry Finger authored
    When rtl8192ce is in operation, kmemleak indicates a number of leaks, yet
    when the driver is removed all are gone. These false positives happen
    in two locations:
    
    unreferenced object 0xffff880041124000 (size 9536):
      comm "work_for_cpu", pid 9295, jiffies 4295037203 (age 20596.320s)
