From e9647d1e74a9778539ad3232e58833210c1935f5 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Thu, 5 Mar 2015 15:09:29 +0100 Subject: [PATCH] net: fec: fix unbalanced clk disable on driver unbind When the driver is removed (e.g. using unbind through sysfs), the clocks get disabled twice, once on fec_enet_close and once on fec_drv_remove. Since the clocks are enabled only once, this leads to a warning: WARNING: CPU: 0 PID: 402 at drivers/clk/clk.c:992 clk_core_disable+0x64/0x68() Remove the call to fec_enet_clk_enable in fec_drv_remove to balance the clock enable/disable calls again. This has been introduce by e8fcfcd5684a ("net: fec: optimize the clock management to save power"). Signed-off-by: Stefan Agner Acked-by: Fugang Duan Signed-off-by: David S.
