Subject: [PATCH 2/2] dma: imx-sdma: Adding tasklet_kill() in sdma_remove function.
Date: Wed, 30 Jul 2014 18:41:15 +0530	[thread overview]
Message-ID: <1406725875-9171-3-git-send-email-Vignesh_Raman@mentor.com> (raw)
In-Reply-To: <1406725875-9171-1-git-send-email-Vignesh_Raman@mentor.com>

Several dma drivers calls tasklet_kill() in remove function. This is missing in
imx driver, so adding tasklet_kill() in sdma_remove function.
