Subject: tests: Reset WARN_ON_ONCE() state in the kernel
X-Git-Tag: hostap_2_11~678
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=31792fa8d980e12033fa839a87b0e5d7c18e5de2;p=thirdparty%2Fhostap.git

tests: Reset WARN_ON_ONCE() state in the kernel

If a tests hits a WARN_ON_ONCE then the retriggering will make it appear
to pass, since the warning will not happen again. Make this more
reliable by resetting the states at the beginning of each test.
