From 6a2f18cf58a59ba7de2a5f912b12d9732702969c Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 13 May 2013 01:49:13 -0300 Subject: [PATCH] [media] s5p-tv: fix error return code in mxr_acquire_video() Fix to return a negative error code in the vb2_dma_contig_init_ctx() error handling case instead of 0, as done elsewhere in this function. Also vb2_dma_contig_init_ctx() return ERR_PTR() in case of error and never return NULL, so use IS_ERR() replace IS_ERR_OR_NULL().
