If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/media/platform/rcar-fcp.ko | grep alias alias: rcar-fcp After this patch: $ modinfo drivers/media/platform/rcar-fcp.ko | grep alias alias: rcar-fcp alias: of:N*T*Crenesas,fcpvC* alias: of:N*T*Crenesas,fcpv alias: of:N*T*Crenesas,fcpfC* alias: of:N*T*Crenesas,fcpf Signed-off-by:

As reported by smatch: drivers/media/usb/usbtv/usbtv-video.c:716 usbtv_s_ctrl() error: doing dma on the stack (data) drivers/media/usb/usbtv/usbtv-video.c:758 usbtv_s_ctrl() error: doing dma on the stack (data) We should not do it, as it won't work on Kernels 4.9 and upper. So, alloc a buffer for it. Fixes: c53a846c ("[media] usbtv: add video controls") Signed-off-by:

The devm_ioremap_resource() returns error pointers, never NULL. The platform_get_resource() returns NULL on error, never error pointers. The error code needs to be set, as well. The current code returns PTR_ERR(NULL) which is success. Fixes: 57b2c062 ("[media] st-hva: multi-format video encoder V4L2 driver") Signed-off-by:

A bugfix removed the two callers of s5p_cec_runtime_suspend and s5p_cec_runtime_resume, leading to the return of a harmless warning that I had previously fixed in commit aee89370 ("[media] s5p_cec: mark suspend/resume as __maybe_unused"): staging/media/s5p-cec/s5p_cec.c:234:12: error: ‘s5p_cec_runtime_suspend’ defined but not used [-Werror=unused-function] staging/media/s5p-cec/s5p_cec.c:242:12: error: ‘s5p_cec_runtime_resume’ defined but not used [-Werror=unused-function] This adds the __maybe_unused annotations to the function that were not removed and that are now unused when CONFIG_PM is disabled.

* A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kcalloc". This issue was detected by using the Coccinelle software. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
