From: Jarkko Nikula Date: Wed, 13 Feb 2008 09:47:29 +0000 (+0200) Subject: ARM: OMAP: Pass logical DMA channel number always to callback handlers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=538528de0cb256f65716ab2e9613d9e920f97fe2;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git ARM: OMAP: Pass logical DMA channel number always to callback handlers This makes parameter passing to DMA handlers uniform between non-chained and chained transfers and makes debugging easier. Additional data like chain_id can be always passed to handlers via callback data if needed.
