wait_for_completion_timeout() returns 0 on timeout and aleast 1 otherwise so checking for < makes no sense here. Signed-off-by: Nicholas Mc Guire <hofrat@xxxxxxxxx> --- Problem located with an experimental coccinelle script While this check does no harm in this form - it should be fixed anyway to comply with the API see: kernel/sched/completion.c Also noticed that get_maintainer.pl will not list linux-kernel@xxxxxxxxxxxxxxx when run on drivers/gpu/drm/msm/dsi/dsi_host.c - is that intentional ?
