This is still unindented! :)
Also GCC doesn't trust you with removal of the parenthesis:

../drivers/net/dsa/mt7530-mdio.c:149:18: warning: suggest parentheses around ‘-’ in operand of ‘&’ [-Wparentheses]
  149 | return (phy_addr - MT7530_NUM_PORTS & ~MT7530_NUM_PORTS) + MT7530_NUM_PORTS & PHY_MAX_ADDR - 1;
../drivers/net/dsa/mt7530-mdio.c:149:58: warning: suggest parentheses around ‘+’ in operand of ‘&’ [-Wparentheses]
  149 | return (phy_addr - MT7530_NUM_PORTS & ~MT7530_NUM_PORTS) + MT7530_NUM_PORTS & PHY_MAX_ADDR - 1;

even your you're correct.
