Looks good to me. Actually, the point is if edev->desc->ops->get_event() fails, the code in devfreq_event_get_event() will reset edata->total_count and edata->load_count to 0.

You're right. devfreq_event_get_event() initializes the data when before calling edev->desc->ops->get_event() or fail happen.

This is done by devfreq_event_get_event() so remove the redundant code in exynos_nocp_get_event(). Signed-off-by: Axel Lin <axel.lin@ingics.com> --- drivers/devfreq/event/exynos-nocp.c | 3 --- 1 file changed, 3 deletions(-)
