Subject: libcrc32c: Fix "crc32c undefined" compilation error
X-Git-Tag: v2.6.29-rc1~589^2~35
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=53b146ae598268edbe2bf7ea7dfec721d51adddd;p=linux-2.6-omap-h63xx.git

libcrc32c: Fix "crc32c undefined" compilation error

The latest shash changes leave crc32c undefined:

[...]
Building modules, stage 2.
  MODPOST 1381 modules
  ERROR: "crc32c" [net/sctp/sctp.ko] undefined!
  ERROR: "crc32c" [net/ipv4/netfilter/nf_nat_proto_sctp.ko] undefined!

Adding EXPORT_SYMBOL(crc32c) to lib/libcrc32c.c fixes the compile error.
This patch has been compile-tested only.
