I didn't get the cover letter. I added the IS_ERR, check as you suggested. That caused a rebase of the other patches as well. Sorry if it was unclear. Kind regards Uffe

It also applies on "git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik.git" on the i2c-nomadik, which already holds Linus's patch. This is what I thought was important due what's stated in the MAINATAINERS file. Now, I guess I should use your tree instead, "git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git". Any particular branch I should use? Maybe it's also better if I just resend the patches in a new patchset, once I rebased them towards your tree?

Sorry, I have taken Linus v1 patch as base, it should have been v2 of course. Sorry for wasting your time. I will rebase and send v4 patches asap.
