Statically allocated array of pointed to hwmon_channel_info can be made
const for safety.

This depends on hwmon core patch:
https://lore.kernel.org/all/[email protected]/
Therefore I propose this should also go via hwmon tree.

I am not going to apply patches for 10+ subsystems through the hwmon tree.
This can only result in chaos. The dependent patch is available at
git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging.git hwmon-const
or wait until after the next commit window to apply this patch.

Doesn't it cause build errors or warnings there?

Are you saying that "hwmon: constify pointers to hwmon_channel_info" applied on its own
on top of v6.3-rc5 (as done in above branch) causes build errors or warnings ?
I have not seen any such reports, and I don't immediately see why that would be
the case. Please elaborate.

My tree and patches are extensively tested by kbuild and there was no
warning reported (when the above patch is applied with above dependency).
Best regards,

I don't know, I assumed the vdpa patch fixes build. If not,
I think we can just wait with the vdpa patch until after
the hwmon one is upstream.

If build is ok we can just wait for hwmon patch to get upstream. No
rush.
