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 #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. _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
