Generic detection leads to too many false positives, so drop it. FWIW sensors-detect does not have such generic detection. If the user wants to force the driver to bind to a not yet supported chip, he/she can still do so using sysfs attribute new_device.

That will put your name and e-mail address in the kernel development logs though, so up to you. drivers/hwmon/lm85.c | 33 ++++++++++----------------------- 1 file changed, 10 insertions(+), 23 deletions(-) --- linux-3.15-rc7.orig/drivers/hwmon/lm85.c 2014-03-31 05:40:15.000000000 +0200 +++ linux-3.15-rc7/drivers/hwmon/lm85.c 2014-06-11 15:45:35.967963827 +0200 @@ -5,7 +5,7 @@ * Copyright (c) 2002, 2003 Philip Pokorny <ppokorny@xxxxxxxxxxxxxxxxxxxx> * Copyright (c) 2003 Margit Schubert-While <margitsw@xxxxxxxxxxx> * Copyright (c) 2004 Justin Thiessen <jthiessen@xxxxxxxxxxxxxxxxxxxx> - * Copyright (C) 2007--2009 Jean Delvare <jdelvare@xxxxxxx> + * Copyright (C) 2007--2014 Jean Delvare <jdelvare@xxxxxxx> * * Chip details at <http://www.national.com/ds/LM/LM85.pdf> * @@ -39,7 +39,7 @@ static const unsigned short normal_i2c[] = { 0x2c, 0x2d, 0x2e, I2C_CLIENT_END }; enum chips { - any_chip, lm85b, lm85c, + lm85, adm1027, adt7463, adt7468, emc6d100, emc6d102, emc6d103, emc6d103s }; @@ -75,9 +75,6 @@ enum chips { #define LM85_COMPANY_NATIONAL 0x01 #define LM85_COMPANY_ANALOG_DEV 0x41 #define LM85_COMPANY_SMSC 0x5c -#define LM85_VERSTEP_VMASK 0xf0 -#define LM85_VERSTEP_GENERIC 0x60 -#define LM85_VERSTEP_GENERIC2 0x70 #define LM85_VERSTEP_LM85C 0x60 #define LM85_VERSTEP_LM85B 0x62 #define LM85_VERSTEP_LM96000_1 0x68 @@ -351,9 +348,9 @@ static const struct i2c_device_id lm85_i { "adm1027", adm1027 }, { "adt7463", adt7463 }, { "adt7468", adt7468 }, - { "lm85", any_chip }, - { "lm85b", lm85b }, - { "lm85c", lm85c }, + { "lm85", lm85 }, + { "lm85b", lm85 }, + { "lm85c", lm85 }, { "emc6d100", emc6d100 }, { "emc6d101", emc6d100 }, { "emc6d102", emc6d102 }, @@ -1281,7 +1278,7 @@ static int lm85_detect(struct i2c_client { struct i2c_adapter *adapter = client->adapter; int address = client->addr; - const char *type_name; + const char *type_name = NULL; int company, verstep; if (!i2c_check_functionality(adapter, I2C_FUNC_SMBUS_BYTE_DATA)) { @@ -1297,16 +1294,6 @@ static int lm85_detect(struct i2c_client "Detecting device at 0x%02x with COMPANY: 0x%02x and VERSTEP: 0x%02x\n", address, company, verstep); - /* All supported chips have the version in common */ - if ((verstep & LM85_VERSTEP_VMASK) != LM85_VERSTEP_GENERIC && - (verstep & LM85_VERSTEP_VMASK) != LM85_VERSTEP_GENERIC2) { - dev_dbg(&adapter->dev, - "Autodetection failed: unsupported version\n"); - return -ENODEV; - } - type_name = "lm85"; - - /* Now, refine the detection */ if (company == LM85_COMPANY_NATIONAL) { switch (verstep) { case LM85_VERSTEP_LM85C: @@ -1323,6 +1310,7 @@ static int lm85_detect(struct i2c_client "Found Winbond WPCD377I, ignoring\n"); return -ENODEV; } + type_name = "lm85"; break; } } else if (company == LM85_COMPANY_ANALOG_DEV) { @@ -1357,12 +1345,11 @@ static int lm85_detect(struct i2c_client type_name = "emc6d103s"; break; } - } else { - dev_dbg(&adapter->dev, - "Autodetection failed: unknown vendor\n"); - return -ENODEV; } + if (!type_name) + return -ENODEV; + strlcpy(info->type, type_name, I2C_NAME_SIZE); return 0; -- Jean Delvare SUSE L3 Support _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
