Changes by: zkabelac@sourceware.org 2010-11-30 22:28:06
Modified files:
lib/activate : dev_manager.c dev_manager.h
Log message:
Remove check for lv is NULL
'lv' is deferenced in the begining of the function so any check
later is not helpful.
Parameters for dev_manager_transien() are marked as nonnull.
