From: Philippe Reynes Date: Thu, 9 Jan 2020 16:34:02 +0000 (+0100) Subject: test/cmd_ut.c: fix cmd_ut_category X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3f05f087c37ec6b408dfd3b0a864c59749b5b8e1;p=u-boot.git test/cmd_ut.c: fix cmd_ut_category In the function cmd_ut_category, the prefix is used with the function strncmp to know if the prefix should be removed from the test name, even if the prefix is NULL. To avoid this issue, we consider that a prefix NULL mean no prefix. So we only try to remove the prefix from the test_name if the prefix is not NULL, then we avoid to call the function strncmp with a NULL prefix.
