[PATCH] drvres: Improve grp->id setting logics in devres_open_group()

From: Liu Ying
Date: Wed Oct 29 2014 - 06:10:57 EST


Instead of setting grp->id directly with a temporary value and
then changing it if a certain condition meets, we may check
the condition first and then decide which value should be set
to grp->id. This may save two lines of code and potentially
reduces a writing operation.
