media: v4l2-async: Improve v4l2_async_notifier_add_*_subdev() API

2021-02-06T08:18:53Z

The functions that add an async subdev to an async subdev notifier take as an argument the size of the container structure they need to allocate. This is error prone, as passing an invalid size will not be caught by the compiler. Wrap those functions in macros that take a container type instead of a size, and cast the returned pointer to the desired type. The compiler will catch mistakes if the incorrect type is passed to the macro, as the assignment types won't match.

media: v4l2-async: Clean v4l2_async_notifier_add_fwnode_remote_subdev

2021-02-06T07:40:36Z

Change v4l2_async_notifier_add_fwnode_remote_subdev semantics so it allocates the struct v4l2_async_subdev pointer. This makes the API consistent: the v4l2-async subdevice addition functions have now a unified usage model. This model is simpler, as it makes v4l2-async responsible for the allocation and release of the subdevice descriptor, and no longer something the driver has to worry about. On the user side, the change makes the API simpler for the drivers to use and less error-prone.

media: omap3isp: Remove misleading comment

2020-12-02T14:55:12Z

in_interrupt() covers hard and soft interrupt servicing and bottom half disabled contexts, which is semantically undefined and useless. The comment for __ccdc_lsc_configure() "Context: in_interrupt()" is therefore as useful as "Context: unknown'. Remove it.

media: omap: Replace HTTP links with HTTPS ones

2020-09-01T12:13:27Z

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

After mm.h was removed from the asm-generic version of cacheflush.h, s390 allyesconfig shows several warnings of the following nature: In file included from arch/s390/include/generated/asm/cacheflush.h:1, from drivers/media/platform/omap3isp/isp.c:42: include/asm-generic/cacheflush.h:16:42: warning: 'struct mm_struct' declared inside parameter list will not be visible outside of this definition or declaration As Geert and Laurent point out, this driver does not need this header in the two files that include it. Remove it so there are no warnings.
