hwmon: (tmp401) Do not auto-detect chip on I2C address 0x37

2015-05-29T20:37:06+00:00

I2C address 0x37 may be used by EEPROMs, which can result in false
positives. Do not attempt to detect a chip at this address.

hwmon: (tmp401) Bail out from tmp401_probe() in case of write errors

2014-12-04T19:00:44+00:00

The return value of i2c_smbus_read_byte_data() is checked in
tmp401_init_client(), but only a warning is printed and the device is
registered anyway. This leads to devices being registered even if they
cannot be physically detected.

Bail out from probe in case of write errors and notify the user.

hwmon: (tmp401) Drop redundant safety on cache lifetime

2013-05-19T15:19:29+00:00

time_after (as opposed to time_after_equal) already ensures that the
cache lifetime is at least as much as requested. There is no point in
manually adding another jiffy to that value, and this can confuse the
reader into wrong interpretation.
