Invoke cn_netlink_send() in a work context as opposed being called in the context of channel callback. On entry into the channel callback code the channel inbound spin lock is held and deferring to a work context avoids having to invoke cn_netlink_send() while holding the inbound lock. As part of this adjustment, also increase the timeout value for waiting for the user level component of KVP. Signed-off-by:

The host gurantees that there can be only one kvp transaction active against the guest. So, the transaction active state is needed only to protect against spurious user level calls. The current code had a race condition where the guest could prematurely return because the previous transaction state was not cleared - this state was being cleared after sending the response to the host and there was a window where the host could notify the guest of a new transaction before the transaction active state was properly set. Also deal with the case when the user mode component does not respond in a timely fashion correctly. I would like to thank Long Li <longli@microsoft.com> for identifying the problem. Signed-off-by:

Basically make use of the gpio array functions. Technically the free doesn't need as much info as given here, but this keeps it clean and easy to follow. Signed-off-by:

This is needed to ensure the required name attribute is created. Using an id table is the route most consistent with other drivers. Signed-off-by:

There are far too many possible part numbers that are not covered in here to have such a generic name. So move to naming after one of the supported parts. Signed-off-by:

Ensure naming reflects what is measured, not how it is done. Resolvers can measure the same thing for starters. IIO_GYRO->IIO_ANGL_VEL to ensure consistent naming. Signed-off-by:

Scraps the pointless name define and adds an id table. It's not technically required in drivers with only one supported part but it does make the probe code more consistent. Signed-off-by:

When the new allocation code was introduced a stray pointer to iio_dev structure was left in the chip state structure. This was never set but was then registered with the core. Signed-off-by:

Throughout the data structures within the driver several references to the driver variables were stored. As the storage and access functions are now consolidated into srom.c those references are no longer needed and have been removed. Reviewed-by:

The driver variables from srom are stored in memory with string identifiers and the caller needed to use this string identifier to retrieve a driver variable. The commit changes the calling code replacing strings with enumerated identifiers. Reported-by:

The phy code used its own driver variable lookup functions which were duplicates of those in the brcmsmac driver (in srom.c). The phy code now uses the functions in srom.c through the phy_shim interface. Reviewed-by:

The driver uses variables which are stored in string format. Using strings as variable identifiers is disliked by the community. The driver has been cleaned up and the only module providing these variables is srom.c. The variable retrieval functions have been moved to srom.c in preparation of a more likable way to store and lookup these driver variables. Reported-by:
