Subject[PATCH 5.4 48/64] igc: igc_write_phy_reg_gpy: drop premature return
Date
From: Sasha Neftin <sasha.neftin@intel.com>

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.

Fixes: 5586838fe9ce ("igc: Add code for PHY support")
