Lockdep is complaining about recursive locking, because it can't make a difference between locked skb_queues. Annotate nested locks and avoid double bh_disable/enable.

We do not currently provide routing information for NI PCIe-6251 and PCI-6259 boards, but they are functionally identical to the PCI-6251 and PCI-6259 boards and can share their routing information. (This has been confirmed for the PCIe-6251 by Éric Piel, using the "NI MAX" software for Windows. It is hoped that it applies to PCIe-6259, but has not yet been checked due to lack of hardware.) Initialize the `alt_route_name` member of the board information for PCIe-6251 and PCIe-6259 to allow them to make use of the routing information provided for PCI-6251 and PCI-6259 respectively.

We do not have or do not provide routing information for all supported boards. Some of the boards for which we do not provide routing information actually have routes that are identical to a similar board for which we already provide routing information. To allow boards to share identical routing information, add an `alt_route_name` member to `struct ni_board_struct`. This will be initialized to `NULL` for all boards except those that will use make use of the identical routing information that has been provided for a similar board, in which case it will name that board. Pass the `alt_route_name` member value to `ni_assign_device_routes()` as the `alt_board_name` parameter, which it will use if no routing information could be found for the actual board name.

We do not have or provide routing information available for all supported boards. Some of the boards for which we do not currently provide routing information actually have identical routes to a similar board for which we do provide routing information. To avoid having to provide duplicate routing information, add an "alternate board name" parameter (possibly `NULl`) to `ni_assign_device_routes()` and `ni_find_device_routes()`. If the routing information cannot be found for the actual board name, try finding it using the alternate board name. Cc: Éric Piel <piel@delmic.com> Cc: Spencer E.

Split out the loops in `ni_find_valid_routes()` into separate functions: * ni_find_route_values(device_family) to find the list of route values for a device family (e.g "ni-mseries"); and * ni_find_valid_routes(board_name) to find the set of valid routes for a board name. The functions above return `NULL` if the information is not found (as we do not currently have the routing information available for all supported boards).

The vol_type variable is always set to 'EXFAT'. The variable checks are unnessesary, so remove unused code. Signed-off-by:

Refactor SPI commands handling by making use of 'struct' for data exchange and extraction of information flow between host and firmware. The SPI read/write commands are now handled in separate function instead of using a single function to process all types of command. The use of 'struct' helped to make the code self explanatory. These points were discussed and suggested during code review [1]. 1. https://www.spinics.net/lists/linux-wireless/msg191489.htmlSigned-off-by:
