Revision 14e3995e63759b80eb22a3c06958d105db4d3f79 authored by Wei Yongjun on 16 May 2017, 14:22:47 UTC, committed by Stefano Stabellini on 18 May 2017, 18:42:32 UTC
In case of error, the function xenbus_read() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
