From: Michael S. Tsirkin Date: Thu, 1 Oct 2009 17:30:49 +0000 (+0200) Subject: hw/omap_dma: add matching {} in if 0 X-Git-Tag: TizenStudio_2.0_p2.3~7344 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d71fd553b73fcdbb07e7af28ef937eb3dd00c776;p=sdk%2Femulator%2Fqemu.git hw/omap_dma: add matching {} in if 0 MULTI_REQ is never defined, so it doesn't matter much, but since we have an if statement there, let's add {} to clarify what it should do if it's uncommented, and indent the code properly.
