Currently, one would have to put a loop on the address transfer waiting an ack
is received in user space.
This is what most i2c master drivers would need to do anyhow. I have
never heard of hardware support for that. Do you know an IP core which

Of_node_put supports NULL as its argument, so the initial test is not
necessary.
Suggested by Uwe Kleine-König.
The semantic patch that fixes this problem is as follows:
: always enable HSI2C
Uwe Kleine-König (1):
i2c: efm32: correct namespacing of location property
Vincent Palatin (1):
i2c: s3c2410: resume the I2C controller earlier
Wolfram Sang (19):
i2c: s6000: remove duplicate driver
i2c: scx200: drop GPIO based i2c driver
i2c: add
. So this patch adds a statement to jump to the fail lable to release the
clocks.

strncpy(kim_data-dev_name, buf, count);
+ kim_data-dev_name[count - 1] = '\n';
Of course this does not add termination, but adds a newline at the end of the
buffer? Huh?
strlcpy?

The SMBus host controller is the same as used in Baytrail so add the new
PCI ID to the driver's list of supported IDs.

Added driver to support the MEN Board Information EEPROM.
The driver exports the production information as read only sysfs
entries, as well as a user section which is read/write accessible.
Tested on PPC QorIQ and Intel Atom

I do not want to parse the things in userspace because this EEPROM data
are related to the hardware and i want to give our customer the easiest way
to access the data without installing any tool.
I understand that point of view. From an upstream point of view, things
may look different,

Most customers wants just to have a running system without installing
anything.
And for me an EEPROM is so simple and should not need a complicated way
to access it.
As I pointed out, there are ways to do it other than a seperate driver.
Yes of course there are a lot of possibilities.
Here it gets frustrating. It seems you have no idea what an OS is for,
not even after I tried to describe it :(
Sorry, that might have been too strong. Still, we can't map any hardware
which is out there 1:1 into userspace, we need abstraction.
If you want to help with this abstraction, this
Commit 9447057eaff8 (platform_device: use a macro instead of
platform_driver_register) introduced a codepath which could result into
drivers having no owner. This went unnoticed for months, so add a
warning in case this happens again somewhere else somewhen.
