If two keys are pressed, then both keys are encoded in the scancode. This makes the mce keyboard more responsive. Signed-off-by:

The mce keyboard repeats pressed keys every 100ms. If the IR timeout is set to less than that, we send key up events before the repeat arrives, so we have key up/key down for each IR repeat. The keyboard ends any sequence with a 0 scancode, in which case all keys are cleared so there is no need to run the timeout timer: it only exists for the case that the final 0 was not received.

Each IR protocol has its own repeat period. We can minimise the keyup timer to be the protocol period + IR timeout. This makes keys less "sticky" and makes IR more reactive and nicer to use. This feature was previously attempted in commit d57ea877 ("media: rc: per-protocol repeat period"), but that did not take the IR timeout into account, and had to be reverted. Signed-off-by:

The longer the IR timeout, the longer the rc device waits until delivering the trailing space. So, by reducing this timeout, we reduce the delay for the last scancode to be delivered. Note that the lirc daemon disables all protocols, in which case we revert back to the default value. Signed-off-by:

On the raspberry pi, we might have two lirc devices; one for sending and one for receiving. This change makes it much more apparent which one is which. Signed-off-by:

The OMAP3 ISP driver manages its MMU mappings through the IOMMU-aware ARM DMA backend. The current code creates a dma_iommu_mapping and attaches this to the ISP device, but never detaches the mapping in either the probe failure paths or the driver remove path resulting in an unbalanced mapping refcount and a memory leak. Fix this properly. Reported-by:

In the past, "up" were an acronym for "user pointer" and "kp" for "kernel pointer". However, since commit a1dfb4c4 ("media: v4l2-compat-ioctl32.c: refactor compat ioctl32 logic"), both are now __user pointers. So, the usage of "kp" is really misleading there. So, rename both to just "p32" and "p64" everywhere it occurs, in order to make peace with this file's namespace. There are two exceptions to "up/kp" nomenclature: at alloc_userspace() and at do_video_ioctl(). There, a new userspace pointer were allocated, in order to store the 64 bits version of the ioctl. Those were called as "up_native", with is, IMHO, an even worse name, as "native" could mislead of being the arguments that were filled from userspace. I almost renamed it to just "p64", but, after thinking more about that, it sounded better to call it as "new_p64", as this makes clearer that this is the data structure that was allocated inside this file in order to be used to pass/retrieve data when calling the 64-bit ready file->f_op->unlocked_ioctl() function.

The check for a valid ptr in ddb_io->dma isn't really necessary since only devices that do data transport using DMA are supported by the driver, and all previous initialisation code (through input_init(), output_init() and dma_init(), has_dma is always true as it's set in ddb_probe() during driver load) guarantees the ptr is set. As a side effect, this silences these sparse warnings (albeit them being false positives as ddb_io->dma won't change in these functions so the condition always equals to the same result): drivers/media/pci/ddbridge/ddbridge-core.c:495:9: warning: context imbalance in 'ddb_output_start' - different lock contexts for basic block drivers/media/pci/ddbridge/ddbridge-core.c:510:9: warning: context imbalance in 'ddb_output_stop' - different lock contexts for basic block drivers/media/pci/ddbridge/ddbridge-core.c:525:9: warning: context imbalance in 'ddb_input_stop' - different lock contexts for basic block drivers/media/pci/ddbridge/ddbridge-core.c:560:9: warning: context imbalance in 'ddb_input_start' - different lock contexts for basic block Signed-off-by:Daniel Scheller <d.scheller@gmx.net> Signed-off-by:

Changeset dc9f65cf ("media: staging: atomisp: avoid a warning if 32 bits build") was meant to solve an impossible condition when building with 32 bits. It turns that this impossible condition also happens wit 64 bits: drivers/staging/media/atomisp/platform/intel-mid/atomisp_gmin_platform.c:698 gmin_get_config_var() warn: impossible condition '(*out_len > (~0)) => (0-u64max > u64max)' After a further analysis, this condition will always be false as, on all architectures, size_t doesn't have more bits than unsigned long. Also, the only two archs that really matter are x86 and x86_64, as this driver doesn't build on other archs (as it depends on X86-specific UEFI support). So, just drop the useless code.

The 'from' variable at preview_config() expects an __user * type. However, the logic there does: from = *(void * __user *) ((void *)cfg + attr->config_offset); With actually means a void pointer, pointing to a void __ user pointer. When the first pointer is de-referenced with *(foo), the type it returns is "void *" instead of "void __user *". Change it to: from = *(void __user **) ((void *)cfg + attr->config_offset); in order to obtain, when de-referenced, a void __user pointer, as desired. That prevent those warnings: drivers/media/platform/omap3isp/isppreview.c:893:45: warning: incorrect type in initializer (different address spaces) drivers/media/platform/omap3isp/isppreview.c:893:45: expected void [noderef] <asn:1>*from drivers/media/platform/omap3isp/isppreview.c:893:45: got void *[noderef] <asn:1><noident> drivers/media/platform/omap3isp/isppreview.c:893:47: warning: dereference of noderef expression Reviewed-by: -

if v4l2_subdev_call(..., VENC_GET_FLD,...) fails, it currently returns a random value. Instead, return 1. That's probably better than returning 0, as this is very likely what happens in practice with the current code, as as the probably of an unititialized 32 bits integer to have an specific value (0, in this case), is 1/(2^32). An alternative would be to return an error code, and let the caller to hint, based on the past received frame, but that sounds weird. Signed-off-by: -
