8721884209 i2c-isa: Restore driver owner
i2c-isa: Restore driver owner

Commit 2b48716d1d back in January
2006 was a bit overzealous. It removed .owner from all i2c drivers,
including i2c-isa ones, while they still need it.

2b48716d1d [PATCH] I2C: Remove .owner setting from i2c_driver as it's no longer needed
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
drivers that I found in the current tree (if a driver sets the .owner by
hand, it's not a problem, just not needed.)

ada0c2f8fa [PATCH] hwmon: Fix w83627ehf/hf vs PNPACPI conflict (bug #4014)
This patch changes w83627hf and w83627ehf drivers to reserve only ports
0x295-0x296, instead of full 0x290-0x297 range.  While some other
sensors chips respond to all addresses in 0x290-0x297 range, Winbond
chips respond to 0x295-0x296 only (this behavior is implied by
documentation, and matches behavior observed on real systems).  This is
not problem alone, as no BIOS was found to put something at these unused
addresses, and sensors chip itself provides nothing there as well.

But in addition to only respond to these two addresses, also BIOS
vendors report in their ACPI-PnP structures that there is some resource
at I/O address 0x295 of length 2.  And when later this hwmon driver
attempts to request region with base 0x290/length 8, it fails as one
request_region cannot span more than one device.

Due to this we have to ask only for region this hardware really
occupies, otherwise driver cannot be loaded on systems with ACPI-PnP
enabled.

7bef559455 [PATCH] I2C: refactor message in i2c_detach_client
We could refactor the error message 34 different i2c drivers print if
i2c_detach_client() fails in this function itself. Saves quite a few
lines of code. Documentation is updated to reflect that change.

Note that this patch should be applied after Rudolf Marek's w83792d
patches.

2d8672c5a6 [PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (5/9)
Call the ISA chip drivers detection function directly instead of relying
on i2c_detect. The net effect is that address lists won't be handled
anymore, but they were mostly useless in the ISA case anyway (pc87360,
smsc47m1, smsc47b397 had already dropped them).

We don't need to handle multiple devices, all we may need is a way to
force a given address instead of the original one (some drivers already
do: sis5595, via686a, w83627hf), and, for drivers supporting multiple
chips, a way to force one given kind. All this may be added later on
demand, but I actually don't think there will be much demand.

fde0950903 [PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (3/9)
Convert the 10 ISA hardware monitoring drivers (it87, lm78, pc87360,
sis5595, smsc47b397, smsc47m1, via686a, w83627hf, w83627ehf, w83781d) to
explicitely register with i2c-isa. For hybrid drivers (it87, lm78,
w83781d), we now have two separate instances of i2c_driver, one for the
I2C interface of the chip, and one for ISA interface. In the long run,
the one for ISA will be replaced with a different driver type.

At this point, all drivers are working again, except for missing
dependencies in Kconfig.
