Looking at checkpatch I see a few remaining issues that I believe should be
fixed before merging this:
CHECK: spinlock_t definition without comment
#575: FILE: drivers/staging/media/rkisp1/isp_stats.h:43:
+ spinlock_t irq_lock;
CHECK: struct mutex definition without comment
#581: FILE: drivers/staging/media/rkisp1/isp_stats.h:49:
+ struct mutex wq_lock;
CHECK: spinlock_t definition without comment
#1648: FILE: drivers/staging/media/rkisp1/isp_params.h:25:
+ spinlock_t config_lock;
CHECK: spinlock_t definition without comment
#2058: FILE: drivers/staging/media/rkisp1/capture.h:145:
+ spinlock_t vbq_lock;
Once this is done together with the Jacob Chen email clarification
it is ready to be merged for v5.6.
It passes all the sparse/smatch tests, so that's very good.
Regards,
Hans
