   4 Subject: [PATCH 1/2] net: phy: qcom: qca808x: fix logic error in LED
   5  brightness set
   6
   7 In switching to using phy_modify_mmd and a more short version of the
   8 LED ON/OFF condition in later revision, it was made a logic error where
   9
  10 value ? QCA808X_LED_FORCE_ON : QCA808X_LED_FORCE_OFF is always true as
  11 value is always OR with QCA808X_LED_FORCE_EN due to missing ()
  12 resulting in the testing condition being QCA808X_LED_FORCE_EN | value.
  13
  14 Add the () to apply the correct condition and restore correct
  15 functionality of the brightness ON/OFF.
