Hi Laurent, Thanks for your feedback.

Fixing things around the real change in the patch is a red flag for me when reviewing. I have to spend time reviewing such patches by questioning myself as I cant see why the change is needed only later to find out that that line is changed just because we are modifying things in the area anyhow. So whenever I find my self starting to describe more then one change in the commit message I try break it out to it's own patch, even if it's trivial. > > Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> > > > --- > > src/libcamera/v4l2_videodevice.cpp | 2 +- > > 1 file changed, 1 insertion(+), 1 deletion(-) > > > > diff --git a/src/libcamera/v4l2_videodevice.cpp b/src/libcamera/v4l2_videodevice.cpp > > index d88cb0bd0771e545..268de60bc7965f58 100644 > > --- a/src/libcamera/v4l2_videodevice.cpp > > +++ b/src/libcamera/v4l2_videodevice.cpp > > @@ -216,7 +216,7 @@ int V4L2BufferCache::get(const FrameBuffer &buffer) > > use = index; > > > > /* Try to find a cache hit by comparing the planes. */ > > - if (cache_[index] == buffer) { > > + if (entry == buffer) { > > hit = true; > > use = index; > > break; > > -- > Regards, > > Laurent Pinchart

Hence the "While at it, ..." mentions in the commit message :-) Without them I agree it can be confusing. > > Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> > > > > > --- > > > src/libcamera/v4l2_videodevice.cpp | 2 +- > > > 1 file changed, 1 insertion(+), 1 deletion(-) > > > > > > diff --git a/src/libcamera/v4l2_videodevice.cpp b/src/libcamera/v4l2_videodevice.cpp > > > index d88cb0bd0771e545..268de60bc7965f58 100644 > > > --- a/src/libcamera/v4l2_videodevice.cpp > > > +++ b/src/libcamera/v4l2_videodevice.cpp > > > @@ -216,7 +216,7 @@ int V4L2BufferCache::get(const FrameBuffer &buffer) > > > use = index; > > > > > > /* Try to find a cache hit by comparing the planes. */ > > > - if (cache_[index] == buffer) { > > > + if (entry == buffer) { > > > hit = true; > > > use = index; > > > break;

Instead of looking up the index in the storage vector use the reference to it created at the beginning of the loop. Signed-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> --- src/libcamera/v4l2_videodevice.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
