The omap/omap3 and viu drivers are for 32 bit platforms only. There, a pointer has 32 bits.

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 logic at v4l2_fwnode_reference_parse_int_props() is somewhat complex and violates Linux coding style, as it does multiple statements on a single line.

Locked on: line 288 line 295 line 306 line 314 Unlocked on: line 303 The lock implementation for get event is wrong, as, if an interrupt occurs, down_interruptible() will fail, and the routine will call up() twice when userspace calls the ioctl again.

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:Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-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: -

As warned: drivers/staging/media/davinci_vpfe/dm365_ipipe.c:1834 vpfe_ipipe_init() error: we previously assumed 'res' could be null (see line 1797) There's something wrong at vpfe_ipipe_init(): 1) it caches the resourse_size() from from the first region and reuses to the second region; 2) the "res" var is overridden 3 times; 3) at free logic, it assumes that "res->start" is not overridden by platform_get_resource(pdev, IORESOURCE_MEM, 6), but that's not true, as it can even be NULL there. This patch fixes the above issues by: a) store the resources used by release_mem_region() on a separate var; b) stop caching resource_size(), using the function where needed. Signed-off-by: -

The dm365_ipipe_hw.c and dm365_ipipe.c file check if several table pointers, declared at davinci_vpfe_user.h, are filled before using them. The problem is that those pointers come from struct declarations like: struct vpfe_ipipe_yee { ... short table[VPFE_IPIPE_MAX_SIZE_YEE_LUT]; }; So, they can't be NULL!
