From: Jamie Iles Date: Tue, 18 Jan 2011 04:40:55 +0000 (-0800) Subject: Input: tnetv107x-ts - don't treat NULL clk as an error X-Git-Tag: upstream/snapshot3+hdmi~3244^2~266 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ba555461833aa1b5083004492ba97c92d5fccf46;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git Input: tnetv107x-ts - don't treat NULL clk as an error We should use IS_ERR() when checking whether clk_get() succeeded or not since it returns errors by encoding error codes with ERR_PTR().
