From: Alan Cox Date: Mon, 11 Jul 2011 18:40:34 +0000 (+0100) Subject: gma500: don't dynamically allocate the psb_gtt struct X-Git-Tag: v3.1-rc1~232^2~32 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f00dfacb5123f2c439973347bf9ec7ebf3af8719;p=profile%2Fivi%2Fkernel-x86-ivi.git gma500: don't dynamically allocate the psb_gtt struct It's part of the psb_device so just make it part of the struct not a pointer. This does cause a bit of noise shuffling indirections.
