2022-02-28igc: igc_write_phy_reg_gpy: drop premature returnSasha Neftin1-2/+0
Similar to "igc_read_phy_reg_gpy: drop premature return" patch. igc_write_phy_reg_gpy checks the return value from igc_write_phy_reg_mdic and if it's not 0, returns immediately. By doing this, it leaves the HW semaphore in the acquired state. Drop this premature return statement, the function returns after releasing the semaphore immediately anyway. Fixes: 5586838fe9ce ("igc: Add code for PHY support") Suggested-by: Dima Ruinskiy <[email protected]> Reported-by: Corinna Vinschen <[email protected]> Signed-off-by: Sasha Neftin <[email protected]> Tested-by: Naama Meir <[email protected]> Signed-off-by: Tony Nguyen <[email protected]>
