Hi,
This adds extra prints and information for
debugging purposes.
Michal Kazior (3):
ath10k: print wmi version info
ath10k: dump hex bytes with dev string prefix
ath10k: add debug dump for pci rx

HTT version is already printed so print WMI
version as well for consistency.

Heh, I have been thinking about to add something similar.
But if in the future we add the u32 FW IE for WMI version I would like
to print that as well. I guess we could do that with "%d/%d.%d.%d.%d",
the %d being the u32. The idea here being that both version numbers are
good to know.
But of course for now the above is good, just thinking aloud here.

This makes it easier to debug hex dumps on systems

Would it be possible to simplify this to one scnprintf()? Something
like:
linebuflen += scnprintf(linebuf + linebuflen,
sizeof(linebuf) - linebuflen,
"%s%08x: ",
prefix ? prefix : "",
(unsigned int)(ptr - buf));

Yes, that would be good. I don't feel comfortable editing patches with
logic changes like this.
