Subject: m68k: bitops - offset == ((long)p - (long)vaddr) * 8
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=359c47ea71be21c1105ae474e8c90ec3e988bbdf;p=openwrt%2Fstaging%2Fblogic.git

m68k: bitops - offset == ((long)p - (long)vaddr) * 8

Hence use "offset" in find_next_{,zero_}bit(), like is already done for
find_next_{,zero_}bit_le()
