These _setup functions are called from _probe so they can be marked

I2C bus drivers don't have to support I2C_M_REV_DIR_ADDR. It is a
deviation from the I2C specification, which only makes sense to
implement when really needed.

Low priority thread holding the i2c bus mutex could block higher
priority threads to access the bus resulting in unacceptable
latencies. Change the mutex type to rt_mutex preventing priority
inversion.

We no longer need to write the adapter name to a temporary buffer.
We can write it directly to the i2c_adapter's name field. This is
more efficient.

I wanted to add some error logging to the i2c-powermac driver, but
found that it was very difficult due to the way the
i2c_powermac_smbus_xfer function is organized. Refactor the code in
this function so that each low-level function is only called once.

The i2c-powermac driver doesn't support arbitrary multi-message I2C
transactions, only SMBus ones. Make it clear by returning an error if
a multi-message I2C transaction is attempted. This is better than only
processing the first message, because most callers won't recover from
the short transaction. Anyone wishing to issue multi-message
transactions should use the SMBus API instead of the raw I2C API.

request_region should be used with release_region, not request_mem_region.
Geert Uytterhoeven pointed out that in the case of drivers/video/gbefb.c,
the problem is actually the other way around; request_mem_region should be
used instead of request_region.

[ARM] pxamci: call mmc_remove_host() before freeing resources
|
|
mmc_remove_host() will cause the mmc core to switch off the bus power by
eventually calling pxamci_set_ios(). This function uses the regulator or
the GPIO which have been freed already.
This causes the following Oops on module unload.

When detecting power failure, the probe function would reset the clock
time to defined state.
However, the clock's _date_ might still be bogus and a subsequent probe
fails when sanity-checking these values.

including a valid date.

The possible CCR_Y2K register values are 19 or 20 and struct rtc_time's
tm_year is in years since 1900.
The function translating rtc_time to register values assumes tm_year to be
years since first christmas, though, and we end up storing 0 or 1 in the
CCR_Y2K register, which the hardware does not refuse to do.
A subsequent probing of the clock fails due to the invalid value range in
the register, though.
[ And if it didn't, reading the clock would yield a bogus year because
the function translating registers to tm_year is assuming a register
value of 19 or 20. ]
This fixes the conversion from years since 1900 in tm_year to the
corresponding CCR_Y2K value of 19 or 20.

Following issues have been addressed on DA8XX/OMAP-L1XX:
a. Screen misalignment during booting when frame buffer console is
enabled.
b. Driver was configured always in PSEUDOCOLOR mode. This patch
dynamically configures the driver either in PSEUDOCOLOUR or TRUECOLOR
mode depending on bpp.
c. The RED and BLUE offsets were interchanged resulting in wrong
bootup logo colour.
This patch has been tested on DA830/OMAP-L137 and DA850/OMAP-L138 EVMs.

commit 4706b349f was a forward port of a fix that was needed
for SLES10. But in fact it is not needed in mainline because
the earlier commit dd00a99e7a fixes the same problem in a
better way.
Further, this commit introduces a bug in the way it interacts with
the automatic read-error-correction. If, after a read error is
successfully corrected, the same disk is chosen to re-read - the
re-read won't be attempted but an error will be returned instead.
After reverting that commit, there is the possibility that a
read error on a read-only array (where read errors cannot
be corrected as that requires a write) will repeatedly read the same
device and continue to get an error.
So in the "Array is readonly" case, fail the drive immediately on
a read error.

This patch adds the vendor and device id for the Mobilcom Debitel UMTS surf
stick (a.k.a. 4G Systems XSStick W14, MobiData MBD-200HU, ...).
To see these ids, you need to switch the stick to modem operation first
with the help of usb_modeswitch. This makes it switch from 1c9e:f000 to
1c9e:9603 and thus be recognized by the option driver.

On tx channel abort a cppi interrupt is generated for a short time by
setting the lowest bit of the TCPPICOMPPTR register. It is then reset
immediately by clearing the bit. When the interrupt handler is run,
it does not detect an interrupt in the TCPPIMSKSR or RCPPIMSKSR
registers and thus exits early without writing the TCPPIEOIR register.
It appears that this inhibits further cppi interrupts until the handler
is called by chance, f.ex. from davinci_interrupt().
By moving the unmasking of the interrupt below the writes to
TCPPICOMPPTR, no interrupt is generated and no write to TCPPIEOIR is
necessary.

In gadget mode the answer to a control request should be followed by
a zero-length packet if the amount transferred is an exact multiple of
the endpoint's packet size and the requests has its "zero" flag set.
This patch prevents the request from being immediately removed from the
queue when a control IN transfer ends on a full packet and "zero" is set.
The next time ep0_txstate is entered, a zero-length packet is queued and
the request is removed as fifo_count is 0.

The use of urb->actual_length to update tx_outstanding_bytes
implicitly assumes that the number of bytes actually written is the
same as the number of bytes we tried to write. On error that
assumption is violated so just use transfer_buffer_length the number
of bytes we intended to write to the device.
If an error occurs we need to fall through and call
usb_serial_port_softint to wake up processes waiting in
tty_wait_until_sent.
