Subject: [PATCH] bcm43xx: Set both, the DMAmask and the coherent DMAmask.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=4d5a9e0eeb7ec928c6bd55db410f09ed3779bc2a;p=deliverable%2Flinux.git

[PATCH] bcm43xx: Set both, the DMAmask and the coherent DMAmask.

This has a potential to fix the >1G bug. But I can not test that, yet.
