Subject: x86, cleanup: fix description of __fls(): __fls(0) is undefined
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8450e85399031a192ffb34f0f9ac981173db6a31;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

x86, cleanup: fix description of __fls(): __fls(0) is undefined

Ricardo M. Correia spotted that the use of __fls() in fls64() did
not seem to make sense. In fact fls64()'s implementation is fine,
but the description of __fls() was wrong. Fix that.
