As the per patch description, I only changed the debug level in this patch.

You are right for unsigned type %u is the correct. This is why we have %d
since j, echan->ch_num and echan->slot[i] are integer.

I just collapsed the three line of dev_dbg into one and have not really
checked the formats.
For size_t the correct format should be %zu.
I'll fix this up for the next version.

As the per patch description, I only changed the debug level in this patch.
This can be done as a separate patch later IMO as part of a bigger debug cleanup.
