phy_addr_sel_strap is currently bool.

If this is to be changed, it should be set
true or false.

My preference would be:

chip->phy_addr_sel_strap = (reg != 0 && reg != 0xffff);

But perhaps its bool type should be converted
to int as this phy_addr_sel_strap is used as
int several times.

$ git grep phy_addr_sel_strap
drivers/net/dsa/lan9303-core.c: /* depending on the 'phy_addr_sel_strap' setting, the three phys are
drivers/net/dsa/lan9303-core.c: * 'phy_addr_sel_strap' setting directly, so we need a test, which
drivers/net/dsa/lan9303-core.c: * Special reg 18 of phy 3 reads as 0x0000, if 'phy_addr_sel_strap' is 0
drivers/net/dsa/lan9303-core.c: * 0x0000, which means 'phy_addr_sel_strap' is 1 and the IDs are 1-2-3.
drivers/net/dsa/lan9303-core.c: chip->phy_addr_sel_strap = 1;
drivers/net/dsa/lan9303-core.c: chip->phy_addr_sel_strap = 0;
drivers/net/dsa/lan9303-core.c: chip->phy_addr_sel_strap ? "1-2-3" : "0-1-2");
drivers/net/dsa/lan9303-core.c: int phy_base = chip->phy_addr_sel_strap;
drivers/net/dsa/lan9303-core.c: int phy_base = chip->phy_addr_sel_strap;
drivers/net/dsa/lan9303-core.c: if (port == chip->phy_addr_sel_strap) {
drivers/net/dsa/lan9303-core.c: lan9303_phy_write(ds, chip->phy_addr_sel_strap + port,
drivers/net/dsa/lan9303-core.c: chip->ds->phys_mii_mask = chip->phy_addr_sel_strap ? 0xe : 0x7;
include/linux/dsa/lan9303.h: bool phy_addr_sel_strap;
