The batman-adv source code is the only place in the kernel which uses the *_free_ref naming scheme for the *_put functions. Changing it to *_put makes it more consistent and makes it easier to understand the connection to the *_get functions.

Signed-off-by: Sven Eckelmann sven@narfation.org --- v7: - removed patches which are now applied in the branch master - split *_get -> *_put rename patches into smaller patches only renaming single functions v6: - removed patches which are now applied in the branch next - rebased remaining patches on the patch "batman-adv: Avoid recursive call_rcu for batadv_nc_node" which was modified by Marek while he applied the patches (this unfortunately made some of the remaining patches slightly harder to apply) v5: - add hack which allows to compile against stable kernel like 3.2.44 which also added the kref_get_unless_zero function v4: - fix function names in commit messages - fix double whitespace in batadv_tt_orig_list_entry_release kerneldoc - add extra patch for batadv_claim_free_ref kerneldoc fix - change the phrase "free it" in all *_free_ref/*_put functions to "release it" v3: - update copyright year v2: - split patchset into fixes and kref migration to make it easier when the decision is made where each patch will be applied
