The rkisp1_resizer's enum callback 'rkisp1_rsz_enum_mbus_code' calls the enum callback of the 'rkisp1_isp' on it's video sink pad. This is a bug, the resizer should support the same formats supported by the 'rkisp1_isp' on the source pad (not the sink pad). Fixes: 56e3b29f "media: staging: rkisp1: add streaming paths" Signed-off-by:

When debugging issues that involve more than one video queue, messages related to multiple queues get interleaved without any easy way to tell which queue they relate to. Fix this by adding a queue name to vb2_queue, and printing it in all debug messages in the vb2 core and V4L2 layers. If the name isn't set by drivers, it is automatically filled with the queue direction and address. Signed-off-by:

Up until now the VIN was capable to convert any of its supported input mbus formats to any of it's supported output pixel formats. With the addition of RAW formats this is no longer true. This patch invalidates the pipeline by adding a check if given vin input format can be converted to supported output pixel format. Signed-off-by:

pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code. Thus a pairing decrement is needed on the error handling path to keep the counter balanced. Signed-off-by:

Currently we are considering the instances which are available in core->inst list for load calculation in min_loaded_core() function, but this is incorrect because by the time we call decide_core() for second instance, the third instance not filled yet codec_freq_data pointer.

If lirc_dev_init() fails during module initialization, rc_core_init() returns 0 denoting success. This can cause different issues during further operation of the module.

The soc_camera driver is about to be removed, so drop camera support from this board. Note that the soc_camera driver itself has long since been deprecated and can't be compiled anymore (it depends on BROKEN), so camera support on this board has been broken for a long time (at least since 4.9 when the pxa_camera.c was removed from soc_camera). Note that there is a new pxa_camera.c driver that replaced the old soc_camera based driver, but using that would require these boards to be converted to use the device tree. Signed-off-by:

The functions mtk_mdp_register/unregister_component have been created to add / remove items from the list of components. This will eventually enable us to specify a list of components in the device tree instead of hardcoding them into this driver. The list is modified by a single thread at driver probe time, and will not be traversed by another thread until the call to pm_runtime_enable at the end of probing. Signed-off-by:

The mtk-mdp driver uses states to check if the formats have been set on the capture and output when turning the streaming on, setting controls or setting the selection rectangles. Those states are reset when 0 buffers are requested like when checking capabilities. This patch removes all format checks and set one by default as queues in V4L2 are expected to always have a format set. https://linuxtv.org/downloads/v4l-dvb-apis/uapi/v4l/vidioc-streamon.html https://linuxtv.org/downloads/v4l-dvb-apis/uapi/v4l/vidioc-g-ctrl.html https://linuxtv.org/downloads/v4l-dvb-apis/uapi/v4l/vidioc-g-selection.htmlSigned-off-by:

If fw_csr_string() returns -ENOENT, then "name" is uninitialized. So then the "strlen(model_names[i]) <= name_len" is true because strlen() is unsigned and -ENOENT is type promoted to a very high positive value. Then the "strncmp(name, model_names[i], name_len)" uses uninitialized data because "name" is uninitialized. Fixes: 92374e88 ("[media] firedtv: drop obsolete backend abstraction") Signed-off-by:

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.
