hwmon: (lm78) Fix overflow problems seen when writing large temperature limits

2014-09-13T22:41:41Z

commit 1074d683a51f1aded3562add9ef313e75d557327 upstream. On platforms with sizeof(int) < sizeof(long), writing a temperature limit larger than MAXINT will result in unpredictable limit values written to the chip. Avoid auto-conversion from long to int to fix the problem. Cc: Axel Lin Reviewed-by: Axel Lin Signed-off-by: Guenter Roeck [bwh: Backported to 3.2: adjust context] Signed-off-by: Ben Hutchings

hwmon: Prevent some divide by zeros in FAN_TO_REG()

2014-01-03T04:33:30Z

commit 3806b45ba4655147a011df03242cc197ab986c43 upstream. The "rpm * div" operations can overflow here, so this patch adds an upper limit to rpm to prevent that. Jean Delvare helped me with this patch. Signed-off-by: Dan Carpenter Acked-by: Roger Lucas Signed-off-by: Jean Delvare [bwh: Backported to 3.2: adjust context] Signed-off-by: Ben Hutchings

hwmon: (lm78) Become the maintainer

2011-07-25T19:46:11Z

Declare myself the maintainer of the lm78 driver. I still have a running system with one of these chips. Also count myself as a co-author of the driver. With 34 commits over 6 years, it seems fair. Signed-off-by: Jean Delvare

hwmon: (lm78) Make ISA interface depend on CONFIG_ISA

2011-07-25T19:46:11Z

We should only include support for the ISA interface of the LM78/LM79 if CONFIG_ISA is set. Not only this makes the driver somewhat smaller on most architectures, but this also avoids poking at random I/O ports on these architectures. This is very similiar to what was done for the w83781d driver in October 2008. Signed-off-by: Jean Delvare Cc: Dean Nelson

hwmon: (lm78) Avoid forward declarations

2011-07-25T19:46:11Z

Move code around to avoid several forward declarations. Also group ISA-related functions together, to make future changes easier. Signed-off-by: Jean Delvare Cc: Dean Nelson

hwmon: (lm78) Request I/O ports individually for probing

2010-02-05T18:58:36Z

Different motherboards have different PNP declarations for LM78/LM79 chips. Some declare the whole range of I/O ports (8 ports), some declare only the useful ports (2 ports at offset 5) and some declare fancy ranges, for example 4 ports at offset 4. To properly handle all cases, request all ports individually for probing. After we have determined that we really have an LM78 or LM79 chip, the useful port range will be requested again, as a single block. This fixes the driver on the Olivetti M3000 DT 540, at least.

i2c: Drop I2C_CLIENT_INSMOD_2 to 8

2009-12-14T20:17:27Z

These macros simply declare an enum, so drivers might as well declare it themselves. This puts an end to the arbitrary limit of 8 chip types per i2c driver. Signed-off-by: Jean Delvare Tested-by: Wolfram Sang

i2c: Get rid of struct i2c_client_address_data

2009-12-14T20:17:25Z

Struct i2c_client_address_data only contains one field at this point, which makes its usefulness questionable. Get rid of it and pass simple address lists around instead. Signed-off-by: Jean Delvare Tested-by: Wolfram Sang

i2c: Drop the kind parameter from detect callbacks

2009-12-14T20:17:23Z

The "kind" parameter always has value -1, and nobody is using it any longer, so we can remove it. Signed-off-by: Jean Delvare Tested-by: Wolfram Sang
