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 patch fixes the return value of rc_core_init() on the corresponding error handling path. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

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. [1] https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html [2] https://github.com/KSPP/linux/issues/21 [3] commit 76497732 ("cxgb3/l2t: Fix undefined behaviour") Signed-off-by:Gustavo A. R.
