From 744820869166c8c78be891240cf5f66e8a333694 Mon Sep 17 00:00:00 2001 From: Anton Vasilyev Date: Tue, 8 Aug 2017 18:56:37 +0300 Subject: RDMA/ocrdma: Fix permissions for OCRDMA_RESET_STATS Debugfs file reset_stats is created with S_IRUSR permissions, but ocrdma_dbgfs_ops_read() doesn't support OCRDMA_RESET_STATS, whereas ocrdma_dbgfs_ops_write() supports only OCRDMA_RESET_STATS. The patch fixes misstype with permissions. Found by Linux Driver Verification project (linuxtesting.org).
