commit c4208653a327a09da1e9e7b10299709b6d9b17bf upstream.
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.
