Subject: md: use proper little-endian bitops
X-Git-Tag: v3.1-rc1~131^2~53
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a0a02a7ad62b5615b17294c2075e4916f8d1f0a4;p=platform%2Fkernel%2Flinux-exynos.git

md: use proper little-endian bitops

Using __test_and_{set,clear}_bit_le() with ignoring its return value
can be replaced with __{set,clear}_bit_le().
