From b7479990435713b00870df3c1d98ff66f6ef1ba2 Mon Sep 17 00:00:00 2001 From: Mathias Krause Date: Sun, 19 Jun 2016 14:31:30 +0200 Subject: [PATCH] dma-buf: remove dma_buf directory on bufinfo file creation errors Change the error handling in dma_buf_init_debugfs() to remove the "dma_buf" directory if creating the "bufinfo" file fails. No need to have an empty debugfs directory around.
