Subject: fix jffs2 ACLs on big-endian with 16bit mode_t
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=963945bf93e46b9bf71a07bf9c78183e0f57733a;p=linux-beck.git

fix jffs2 ACLs on big-endian with 16bit mode_t

casting int * to mode_t * is not a good thing - on a *lot* of big-endian
architectures mode_t happens to be smaller than int and there it breaks
quite spectaculary...
