minmax: make generic MIN() and MAX() macros available everywhere

2024-07-28T22:49:18Z

This just standardizes the use of MIN() and MAX() macros, with the very traditional semantics. The goal is to use these for C constant expressions and for top-level / static initializers, and so be able to simplify the min()/max() macros. These macro names were used by various kernel code - they are very traditional, after all - and all such users have been fixed up, with a few different approaches: - trivial duplicated macro definitions have been removed Note that 'trivial' here means that it's obviously kernel code that already included all the major kernel headers, and thus gets the new generic MIN/MAX macros automatically. - non-trivial duplicated macro definitions are guarded with #ifndef This is the "yes, they define their own versions, but no, the include situation is not entirely obvious, and maybe they don't get the generic version automatically" case. - strange use case #1 A couple of drivers decided that the way they want to describe their versioning is with #define MAJ 1 #define MIN 2 #define DRV_VERSION __stringify(MAJ) "." __stringify(MIN) which adds zero value and I just did my Alexander the Great impersonation, and rewrote that pointless Gordian knot as #define DRV_VERSION "1.2" instead. - strange use case #2 A couple of drivers thought that it's a good idea to have a random 'MIN' or 'MAX' define for a value or index into a table, rather than the traditional macro that takes arguments. These values were re-written as C enum's instead. The new function-line macros only expand when followed by an open parenthesis, and thus don't clash with enum use. Happily, there weren't really all that many of these cases, and a lot of users already had the pattern of using '#ifndef' guarding (or in one case just using '#undef MIN') before defining their own private version that does the same thing. I left such cases alone. Cc: David Laight Cc: Lorenzo Stoakes Signed-off-by: Linus Torvalds

media: dvb-frontend/mxl5xx: Refactor struct MBIN_FILE_T and MBIN_SEGMENT_T

2024-06-15T08:49:21Z

Replace the older style one-element array with a flexible array member. There does not seem to be any allocation for these structs in the code, so no more code changes are required. The following cocci warnings are fixed: drivers/media/dvb-frontends/mxl5xx_defs.h:182:4-8: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays) drivers/media/dvb-frontends/mxl5xx_defs.h:171:4-8: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays) Signed-off-by: Ricardo Ribalda Signed-off-by: Hans Verkuil

i2c: mux: Remove class argument from i2c_mux_add_adapter()

2024-05-13T14:13:19Z

99a741aa7a2d ("i2c: mux: gpio: remove support for class-based device instantiation") removed the last call to i2c_mux_add_adapter() with a non-null class argument. Therefore the class argument can be removed. Note: Class-based device instantiation is a legacy mechanism which shouldn't be used in new code, so we can rule out that this argument may be needed again in the future.
