Let the drivers specify the name of the I2C-over-AUX adapter to maintain
backwards compatibility in the sysfs when converting to the new
I2C-over-AUX helper infrastructure.
The i915 driver currently uses DPDDC-A to DPDDC-D as names for the DP
i2c adapters. These names show up in the i2c sysfs name attribute. We'd
like to be able to maintain that when switching over to the new helpers.
Due to i2c device and connector cleanup ordering issues we also recently
made the drm device (instead of connector) the parent of the i2c
adapters:

iSCSI needs to be at least aware that a task involves protection
information. In case it does, after the transaction completed libiscsi
will ask the transport to check the protection status of the
transaction.
Unlike transport errors, DIF errors should not prevent successful
completion of the transaction from the transport point of view, but
should be escelated to scsi mid-layer when constructing the scsi
result and sense data.
check_protection routine will return the ascq corresponding to the DIF
error that occured (or 0 if no error happened).

Use modparams to activate protection information support.
pi_enable bool: Based on this parameter iSER will know if it should
support T10-PI. We don't want to do this by default as it requires to
allocate and initialize extra resources. In case pi_enable=N, iSER
won't publish to SCSI midlayer any DIF capabilities.
pi_guard int: Based on this parameter iSER will publish DIX guard type
support to SCSI midlayer. 0 means CRC is allowed to be passed in DIX
buffers, 1 (or non-zero) means IP-CSUM is allowed to be passed in DIX
buffers. Note that over the wire, only CRC is allowed.
In the next phase, it is worth considering passing these parameters
from iscsid via nlmsg. This will allow these parameters to be
