Unfortunately, it's hard to make standalone packages because the kernel
API is changing in every kernel version.  The work is underway to
include the driver into the kernel, which would provide a long term
solution.  Version 0.13 is obsolete, and I don't think any further
standalone releases will be made.

Neither is correct.  The work handlers need to be changed to get the
context correctly.

Please try the current version.  You can get it by installing git and
running

git-clone http://honk.sigxcpu.org/git/at76c503a.git
