From: Sachin Sant sachinp@linux.vnet.ibm.com
[ Upstream commit a6d8a21596df041f36f4c2ccc260c459e3e851f1 ]
Tests under alignment subdirectory are skipped when executed on previous generation hardware, but harness still marks them as failed.
test: test_copy_unaligned tags: git_version:unknown [SKIP] Test skipped on line 26 skip: test_copy_unaligned selftests: copy_unaligned [FAIL]
The MAGIC_SKIP_RETURN_VALUE value assigned to rc variable is retained till the program exit which causes the test to be marked as failed.
This patch resets the value before returning to the main() routine. With this patch the test o/p is as follows:
test: test_copy_unaligned tags: git_version:unknown [SKIP] Test skipped on line 26 skip: test_copy_unaligned selftests: copy_unaligned [PASS]
