During a manual scan, a user can send command to a nonexistent
lun, precisely at the point of max_lun. Normally it's possible
(but not required) that the firmware has the knowledge that it
is an invalid lun. In the particular case when max_lun is 256,
however, the nonexistent lun 256 will be confused with lun 0,
because the lun member in a request message is only u8, and 256
will become 0. So we need to fix the problem, at least, at the
driver level.

For a particular driver error condition, driver was doing double
scsi_dma_unmaps. Driver was calling scsi_dma_unmap in
pmcraid_error_handler and return 0. This pmcraid_error_handler is called
by pmcraid_io_done which will do scsi_dma_unmap again when it has
return 0 from pmcraid_error_handler.

When the hba port gets logged out of the fabric, or other
such transitional state when the physical link is still present,
the driver doesn't receive a loop up asyn event (where the link
data rate currently gets set). Hence send a explicit mailbox command
to get the link rate in such conditions.

BugLink: https://bugs.launchpad.net/ubuntu/+bug/435958
The module alias currently matches any Acer computer but when loaded the
BIOS checks will only succeed on Aspire One models. This causes a invalid
BIOS warning for all other models (seen on Aspire 4810T). This is not
fatal but worries users that see this message. Limiting the moule alias
to models starting with AOA or DOA for Packard Bell.

In March 2008 commit 0ac4a3c2fbbcadc3e96e4dc47d4ae802d66e6f67 ("ACPI: fix
ATA_ACPI build") made CONFIG_ACPI_DOCK be selected by CONFIG_ATA_ACPI because
of a build error when CONFIG_ATA_ACPI=y and CONFIG_ACPI_DOCK=m.
However, in September 2008 commit 898b054f3eec5921320ae8614b5bdd7b07ea5b43
("dock: make dock driver not a module") removed the possibility of having
CONFIG_ACPI_DOCK=m and therefore there is no need for selecting it when
CONFIG_ATA_ACPI=y.
This makes the kernel ~5 Kb smaller for people who don't have a dock by
allowing them to not have ACPI_DOCK compiled-in because of ATA_ACPI=y.

SN06 makes sure we get back a longer buffer which seems to be necessary
going forward as the SNC devices describes more and more devices (or
features more precisely). Moreover SN06 should be called with only the
descriptor offset to make sure we hit the rfkill controlling function
(F124 or F135) with a 0 argument to get a full list of features.

* 'i2c-fixes' of git://git.fluff.org/bjdooks/linux:
i2c-omap: OMAP3: Fix I2C lockup during timeout/error cases
i2c-omap: Don't write IE state in unidle if 0
i2c-bfin-twi: fix CLKDIV calculation
|
|
Current OMAP3 I2C driver code does not follow the correct sequence for soft
reset. Due to this, lock up issues are reported during timeout/error cases.
This patch fixes above issue by disabling I2C controller as per OMAP3430 TRM
for soft reset. As per TRM, I2C controller needs to be disabled as a first
step during soft reset.
Here is correct soft reset sequence:
a. Ensure that the module is disabled
(clear the I2Ci.I2C_CON[15] I2C_EN bit to 0).
b. Set the I2Ci.I2C_SYSC[1] SRST bit to 1.
c. Enable the module by setting I2Ci.I2C_CON[15] I2C_EN bit to 1.
d. Check the I2Ci.I2C_SYSS[0] RDONE bit until it is set to 1 to
indicate the software reset is complete.
Tested on Zoom2, Zoom3, 3430SDP and 3630SDP

Commit ef871432... (i2c-omap: OMAP3: PM: (re)init for every transfer
to support off-mode) introduced a change which make the dev->iestate
contents be written to the OMAP_I2C_IE_REG every time omap_i2c_unidle
is called. Previously, the state was only written if it wasn't equal
to zero.
In omap_i2c_probe, omap_i2c_unidle() is called prior to omap_i2c_init(),
in which case dev->iestate has not yet been initialized and will be set
to zero. Having this value written to the registers causes deadlock
while booting.
As such, this change restores the original functionality.
