Subject: IB: find_first_zero_bit() takes unsigned pointer
X-Git-Tag: v2.6.24-rc1~1453^2~84
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=65d470b3ea52ee1402499d6fcb4632296452e5b1;p=linux-2.6

IB: find_first_zero_bit() takes unsigned pointer

Fix sparse warning

    drivers/infiniband/core/device.c:142:6: warning: incorrect type in argument 1 (different signedness)
    drivers/infiniband/core/device.c:142:6:    expected unsigned long const *addr
    drivers/infiniband/core/device.c:142:6:    got long *[assigned] inuse

by making the local variable inuse unsigned.  Does not affect generated
code at all.
