commit 1252be9ce0ab4f622b8692b648894d09c0df71ce upstream.

The I2C core always reports the MODALIAS uevent as "i2c:&lt;client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So the driver needs to export the I2C table and this
be built into the module or udev won't have the necessary information
to auto load the correct module when the device is added.

commit 9200bc4c28cd8992eb5379345abd6b4f0c93df16 upstream.

Writing a large value into a voltage limit attribute can result
in an overflow due to an auto-conversion from unsigned long to
unsigned int.

<title>hwmon: (mcp3021) Fix broken output scaling</title>

<content type='text'>
commit 347d7e45bd09ce09cbc30d5cea9de377eb22f55c upstream.

The mcp3021 scaling code is dividing the VDD (full-scale) value in
millivolts by the A2D resolution to obtain the scaling factor. When VDD
is 3300mV (the standard value) and the resolution is 12-bit (4096
divisions), the result is a scale factor of 3300/4096, which is always
one.  Effectively, the raw A2D reading is always being returned because
no scaling is applied.

This patch fixes the issue and simplifies the register-to-volts
calculation, removing the unneeded "output_scale" struct member.
