iwlwifi reports Unsupported splx structure

Greetings,
I am using Intel Corporation Wireless 7265 wireless card and using iwlwifi kernel module as the driver.
I can normally use the device, however in startup kernel reports the following error messages:

[    9.350297] iwlwifi 0000:03:00.0: Unsupported splx structure
[    9.417892] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-7265D-24.ucode failed with error -2

[   18.376421] iwlwifi 0000:03:00.0: L1 Disabled - LTR Enabled

My question is, why is this log printed and is it a big problem? What is "Unsupported splx structure"?

Re: iwlwifi reports Unsupported splx structure

AFAIK it isn't a big problem, somewhere I've seen a patch which explains it a little bit more and downgrade it from an error to a warning or info message.
