Makes sense. It didn't occur to me to refer to register offset definitions and check if REG_9346CR really is 16-bit wide. Now that you pointed it out I see it: #define REG_9346CR 0x000A #define REG_EE_VPD 0x000C -Jakub >> diff --git a/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.c >> b/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.c >> index 11fcfda..5f90261 100644 >> --- a/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.c >> +++ b/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.c >> @@ -1928,10 +1928,10 @@ static int rtl8xxxu_read_efuse(struct rtl8xxxu_priv >> *priv) >> u16 val16, efuse_addr, offset; >> u32 val32; >> >> - val16 = rtl8xxxu_read16(priv, REG_9346CR); >> - if (val16 & EEPROM_ENABLE) >> + val8 = rtl8xxxu_read8(priv, REG_9346CR); >> + if (val8 & EEPROM_ENABLE) >> priv->has_eeprom = 1; >> - if (val16 & EEPROM_BOOT) >> + if (val8 & EEPROM_BOOT) >> priv->boot_eeprom = 1; >> >> val32 = rtl8xxxu_read32(priv, REG_EFUSE_TEST); -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
