commit fda2635466cd26ad237e1bc5d3f6a60f97ad09b6 upstream.
igc_read_phy_reg_gpy checks the return value from igc_read_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.
