This patchset modifies the handling of all the operations on the environment (set/import/default) so to unify handling of special variables. On top of that we implement a selective "env default".
A selective "env import" would imply a user API change and should therefore be discussed separately.
Changes in the syntax (user API): - "env default" -f: override write-once variables, -a means all
First patch is a cosmetic prerequisite to the second patch which constifies serial_assign().
Changes from v0: - checkpatch cleanup - removed himport_ex() - removed warning for serial_assign() - env import NOT implemented here
Gerlando Falauto (5): serial: cosmetic checkpatch compliance serial: constify serial_assign() env: unify logic to check and apply changes env: check and apply changes on delete/destroy env: make "env default" selective, check and apply
