 Description   

linux kernel v6.3-rc4-32-g6eb203e1a868
  iov_iter: remove iov_iter_iovec()

Provide a replacement iov_iter_iovec() when one is not provided.

linux kernel v6.3-rc4-34-g747b1f65d39a
  iov_iter: overlay struct iovec and ubuf/len
This renames iov_iter member iov to __iov and now __iov == __ubuf_iovec

Our replacement iov_iter_iovec() needs to handle the changed member names

linux kernel v6.3-rc1-13-g1aaba11da9aa
  driver core: class: remove module * from class_create()

Provide an ll_class_create() to pass THIS_MODULE or not as needed by the current class_create() requirements.
