If the bitstream and the application are incorrectly configuring the reference pictures, the hardware will need to fallback to using some other reference picture. When the post-processor is enabled, the fallback buffer should be a shadow buffer (postproc.dec_q), and not a CAPTURE queue buffer, since the latter is post-processed and not really the output of the decoder core.

list_for_each_entry is able to handle an empty list. The only effect of avoiding the loop is not initializing the index variable. Drop list_empty tests in cases where these variables are not used. Note that list_for_each_entry is defined in terms of list_first_entry, which indicates that it should not be used on an empty list. But in list_for_each_entry, the element obtained by list_first_entry is not really accessed, only the address of its list_head field is compared to the address of the list head, so the list_first_entry is safe. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) <smpl> @@ expression x,e; iterator name list_for_each_entry; statement S; identifier i; @@ -if (!(list_empty(x))) { list_for_each_entry(i,x,...) S - } ... when != i ? i = e </smpl> Signed-off-by:

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

In the irq handler 'rkisp1_params_isr', the lock 'config_lock' should be held as long as the current buffer is used. Otherwise the stop_streaming calback might remove it from the list and pass it to userspace while it is referenced in the irq handler. Signed-off-by:

The two macros RKISP1_CIF_ISP_LSC_{GRAD/SIZE}_TBL_SIZE have the same value which is the number of sectors in the grads and size parameters. Therefore there is no need for two different macros. Replace them with one macro RKISP1_CIF_ISP_LSC_SECTORS_TBL_SIZE. Also use the macro when iterating the arrays instead of hardcoded '4'. Signed-off-by: -

Currently the fields '*_data_tbl' in the struct 'rkisp1_cif_isp_lsc_config' are one dimensional arrays of size 290. The entries are accessed in a nested loop by summing two indexes for the rows and columns. Therefore it fits better to define the arrays as two dimensional arrays of size 17x17. Signed-off-by:

There is no need to request the "idle" pinctrl state in the driver as that is implemented in the driver core and the pinctrl_pm_* API can be used for switching between the default and the idle state. Simplify the pinctrl code to only request and check for the mandatory "default" pinctrl state. Switching between the default/idle pinctrl state is not yet implemented in the driver and this patch doesn't change that. Signed-off-by:

The "idle" pinctrl state is optional as documented in the DT binding. The change introduced by the commit being reverted makes that pinctrl state mandatory and breaks initialization of the whole media driver, since the "idle" state is not specified in any mainline dts. This reverts commit 18ffec75 ("media: exynos4-is: Add missed check for pinctrl_lookup_state()") to fix the regression.

If the VIN device is part of a group of VIN devices (all Gen3 boards) there is no reason to only unregister the group notifier if the VIN that registers the notifier is removed. The VIN that registers the notifier is always the last VIN device to be bound, so keeping the notifier around after any VIN is unbound creates an unbalanced state where no VIN in the group is operational. Fix this by unconditionally unregistering the notifier when any VIN device is unbound. Unregistering the notifier will lead to unbound() being called and all video devices exposed by any VIN instance to be removed. The lock was only needed to protect the check which VIN registers the notifier and is no longer needed. Signed-off-by:
