Thank you for noticing this, I appreciate it !

However, when I run this patch through the scripts/checkpatch.pl
script, it reports
some issues. Could you fix and post v2 please?

checkpatch.pl output follows:

WARNING: Possible unwrapped commit description (prefer a maximum 75
chars per line)
#68:
arcx-anybus.c:(.text+0x9d6): undefined reference to
`__devm_regmap_init_mmio_clk'

ERROR: DOS line endings

total: 1 errors, 1 warnings, 0 checks, 7 lines checked

NOTE: For some of the reported defects, checkpatch may be able to
      mechanically convert to the typical style using --fix or --fix-inplace.

Your patch has style problems, please review.

This seems text/plain messages have crlf set when saved as .eml file,

I do check my v2 patch is not crlf ending, but when save as eml file in

my thunderbird, it becomes crlf ending.

You all need a better email client, mutt handles this just fine, it's
not a problem on my system with my workflow at all :)

So this patch looks fine to me from a formatting point of view.  But
does it do what it says it does, that's up to Sven...

thanks,

Argh, my bad. I use Google Mail -> Download Message, which does
appear to mess up the endings. Luckily, dos2unix fixes it up just fine.
