2024-07-28minmax: add a few more MIN_T/MAX_T usersLinus Torvalds4-7/+7
Commit 3a7e02c040b1 ("minmax: avoid overly complicated constant expressions in VM code") added the simpler MIN_T/MAX_T macros in order to avoid some excessive expansion from the rather complicated regular min/max macros. The complexity of those macros stems from two issues: (a) trying to use them in situations that require a C constant expression (in static initializers and for array sizes) (b) the type sanity checking and MIN_T/MAX_T avoids both of these issues. Now, in the whole (long) discussion about all this, it was pointed out that the whole type sanity checking is entirely unnecessary for min_t/max_t which get a fixed type that the comparison is done in. But that still leaves min_t/max_t unnecessarily complicated due to worries about the C constant expression case. However, it turns out that there really aren't very many cases that use min_t/max_t for this, and we can just force-convert those. This does exactly that. Which in turn will then allow for much simpler implementations of min_t()/max_t(). All the usual "macros in all upper case will evaluate the arguments multiple times" rules apply. We should do all the same things for the regular min/max() vs MIN/MAX() cases, but that has the added complexity of various drivers defining their own local versions of MIN/MAX, so that needs another level of fixes first.

2024-07-26i3c: master: svc: Improve DAA STOP handle code logicFrank Li1-18/+43
The REQUEST_PROC_DAA command behaves differently from other commands. Sometimes the hardware can auto emit STOP, but in other conditions, it cannot. Improves the code logic to better handle these situations. Hardware can auto emit STOP only when the following conditions are met: - The previous I3C device correctly returns a PID and ACKs an I3C address. - A NACK is received when emitting 7E to try to get the next I3C device's PID. In all other cases, a manual STOP emission is needed. The code is changed to emit STOP when break the while loop and 'return 0' only when the hardware can auto emit STOP.
