[packman] Updating broadcom-wl-kpm-desktop for 4.2.x kernel

[thibault.bv]

Hello,

I had this weekend to upgrade my kernel to 4.2.0-1 (x86_64) and it broke 
the package broadcom-wl-kpm-desktop.
The error was from a change in a function's prototype in the kernel (1), 
so I made a patch and I would like it to be available for other users.
Please find the patch in the attached file.

Have a good day,
