bcmwl-kernel-source 6.20.155.1+bdcom-0ubuntu6 Error! Bad return status for module build [error: implicit declaration of function ‘create_proc_entry’]

Status changed to 'Confirmed' because the bug affects multiple users.

I found the same bug while trying to install the latest kernel 3.11.0-031100-generic on Ubuntu 13.04 (x86_64) Mac mini late 2012 with a BCM4331 wireless chipset. The issue seems to be number of changes appeared in proc_fs.h in kernel-3.10.0 which moved from create_proc_entry() to proc_create(). The patch checks the current version of the kernel and uses the appropriate function calls required.

The attachment "Added support for kernel-3.9.0" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

my make log file.

I've been having the same issue with kernel 3.12.0-rc4. Decided to try perinda's patch, it seems to work, but only after I fixed an issue with whitespaces (I had to replace 4 spaces with a single tab).
