From 51a1efe2e84493439db32c07471e835c752a7923 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Tue, 2 Nov 2010 09:52:17 +0800 Subject: [PATCH] dma: intel_mid_dma: fix double free on mid_setup_dma error path We should not call kfree(dma) in mid_setup_dma error path because the memory is allocated in intel_mid_dma_probe and will be freed in intel_mid_dma_probe error path if mid_setup_dma return error.
