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)
arcx-anybus.c:(.text+0x9d6): undefined reference to

ERROR: DOS line endings
#87: FILE: drivers/staging/fieldbus/anybuss/Kconfig:17:
+^Iselect REGMAP_MMIO^M$

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.
