Jean Delvare 72240307e9 hwmon: (gl518sm) Fix the reported fan speed
The fan speeds reported by the gl518sm driver are twice as much as they
should. It's currently reporting the number of pulses per minute, not
rotations per minute, while typical fans emit two pulses per rotation.
This explains why all reports with this driver had very high speed
values (between 9000 to 12000 RPM). Odd that nobody ever actually
complained about this bug.

Now that i2c_add_driver() doesn't need the module owner to be set by
hand, we can delete it from the drivers.  This patch catches all of the

Jean Delvare 8a9947552d [PATCH] i2c: Drop i2c_driver.flags, 2 of 3
Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we
can simply make it the default and drop the flag. If any driver really
doesn't want to be notified when i2c adapters are added, that driver
can simply omit to set .attach_adapter. This approach is also more
robust as it prevents accidental NULL pointer dereferences.

The only thing left in i2c-sensor.h are module parameter definition
macros. It's only an extension of what i2c.h offers, and this extension
is not sensors-specific. As a matter of fact, a few non-sensors drivers
use them. So we better merge them in i2c.h, and get rid of i2c-sensor.h
altogether.
