From 88c08a3fba9954ce0ec3e1eab07c498a419ad7e3 Mon Sep 17 00:00:00 2001 From: Davide Ciminaghi Date: Thu, 19 Apr 2012 12:20:24 +0200 Subject: [PATCH] dmaengine/amba-pl08x : reset phychan_hold on terminate all When a client calls pl08x_control with DMA_TERMINATE_ALL, it is correct to terminate and release the phy channel currently in use (if one is in use), but the phychan_hold counter must also be reset (otherwise it could get trapped in an unbalanced state).
