From: Jarkko Nikula Date: Thu, 29 Jan 2009 16:57:12 +0000 (-0800) Subject: ARM: OMAP: DMA: Fix uninitialized channel flags X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=a92fda194d31d26c1fecd191a03d2dbc5b6ac230;p=linux-2.6-omap-h63xx.git ARM: OMAP: DMA: Fix uninitialized channel flags This has similar symptoms than 66c23551b1b774e2be3c7bdf91c0ebf2c7a3519e where just omap_request_dma, omap_dma_link_lch and omap_dma_unlink_lch can cause incorrect dump_stack(). Here it can happen if channel has been used before and the channel flags variable holds old status.
