Subject: powerpc: Fix find_next_bit on 32-bit
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=00557b59c69ce284e5a61bcfcdbcc3dc867cb2da;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

powerpc: Fix find_next_bit on 32-bit

We had a "64" that didn't get changed to BITS_PER_LONG, resulting
in find_next_bit not working correctly.
