From a2755e1178c33e69a8c0f7a9961d52ce4af8d365 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 14 Sep 2016 23:21:45 -0300 Subject: [PATCH] [media] pxa_camera: fix error return code in pxa_camera_probe() Fix to return error code -ENODEV from dma_request_slave_channel_compat() error handling case instead of 0, as done elsewhere in this function. Also fix to release resources in v4l2_clk_register() error handling.
