From: Sudhakar Rajashekhara Date: Wed, 6 Jan 2010 11:58:36 +0000 (+0530) Subject: davinci: Correct return value of edma_alloc_channel api X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0e6cb8d296308a75e4047fabc752731ff7836182;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git davinci: Correct return value of edma_alloc_channel api Currently, edma_alloc_channel api is returning the channel number without prepending the controller on which the channel was allocated. So, if a channel is allocated on 2nd controller, calls subsequent to edma_alloc_channel would never know that channel was allocated on the 2nd controller, and continue to operate on 1st controller, resulting in edma failure. This patch fixes this issue.
