In addition, patch description should explain why such change is needed, i.e. what it fixes, improves or prepares the code for. > Note: submitted for review at > https://patchwork.kernel.org/patch/2279591/ > This should not be located in patch description, but rather in comments section below, as is the change log. > Signed-off-by: Naveen Krishna Chatradhi <ch.naveen@xxxxxxxxxxx> > Cc: Doug Anderson <dianders@xxxxxxxxxxxx> > Cc: Lars-Peter Clausen <lars@xxxxxxxxxx> > Reviewed-on: https://chromium-review.googlesource.com/172724 > Reviewed-by: Doug Anderson <dianders@xxxxxxxxxxxx> > --- > Changes since v1: > As per discussion at > http://marc.info/?l=linux-kernel&m=136517637228869&w=3 > > Changes since v2: > None. > Rebased and reposting. > > Changes since v3: > 1. commit message change and > 2. removed an unncessary assignment > > Changes since v4: > Moved INIT_COMPLETION call to the starting of the function > > Changes since v5: > INIT_COMPLETION was replaced by reinit_completion > ("tree-wide: use reinit_completion instead of INIT_COMPLETION"). > Use it to avoid the following build error: > undefined identifier 'INIT_COMPLETION' Not really a comment to the patch, but rather a suggestion for future: It is more convenient to read the change log if it goes from newest to oldest order. Otherwise the changes alone look good.
