f8d5e5a8f5 ARM: PNX4008: i2c-pnx: use the same dev_id for request_irq and free_irq
This allows i2c-pnx to free its interrupt handler when the module
is removed or if an error occurs; using the same dev_id for both
request_irq and free_irq is desirable.

45da790ebe i2c-mpc: Do not generate STOP after read.
The driver always ends a read with a STOP condition which
breaks subsequent I2C reads/writes in the same transaction as
these expect to do a repeated START(ReSTART).

This will also help I2C multimaster as the bus will not be released
after the first read, but when the whole transaction ends.

18669eabde i2c: Hide probe errors caused by ACPI resource conflicts
When an ACPI resource conflict is detected, error messages are already

ac7809414f i2c/tsl2550: Use combined SMBus transactions
Make the I/O faster, mainly by using combined SMBus transactions when
possible. While the TSL2550 datasheet doesn't say the device supports
them, they seem to work just fine in practice, and a combined
transaction is faster than two simple transactions in many cases and
always more reliable.

A side effect is to suppress the delays between SMBus writes and
reads. The datasheet doesn't say they are needed and things work just
fine for me without them.

I also couldn't see any reason for the delay between reading the two
channels. Nor for the loop to get a reading in the first place. The
400 ms delay between samples only matters at chip power-up, after that
the chip always hold the previously sampled value so we never get to
wait.

All these changes make reading the lux value much faster and cheaper.

7605fa3b0a i2c-davinci: behave with i2cdetect
Make i2c-davinci cope properly with "i2cdetect":  don't spew
syslog spam on perfectly normal behaviors, or respond to any
address other than the one reserved for the SMBus host.

DaVinci core code has converted to the new clkdev API so

ad361c9884 Remove multiple KERN_ prefixes from printk formats
Commit 5fd29d6ccb ("printk: clean up
handling of log-levels and newlines") changed printk semantics.  printk
lines with multiple KERN_<level> prefixes are no longer emitted as
before the patch.

<level> is now included in the output on each additional use.

Remove all uses of multiple KERN_<level>s in formats.
