From: Ben Hutchings Date: Wed, 25 Nov 2009 16:09:41 +0000 (+0000) Subject: sfc: Clean up struct falcon_board and struct falcon_board_data X-Git-Tag: upstream/snapshot3+hdmi~16449^2~190 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=44838a447de3b1541cbf845853c4f8999310b0dd;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git sfc: Clean up struct falcon_board and struct falcon_board_data Put all static information in struct falcon_board_type and replace it with a pointer in struct falcon_board. Simplify probing aocordingly. Signed-off-by: Ben Hutchings Signed-off-by: David S.
