Subject: [PATCH] aic94xx: don't return zero on failure paths in aic94xx_init()
Date: Sat, 19 May 2018 00:27:18 +0300 [thread overview]
Message-ID: <1526678838-31469-1-git-send-email-khoroshilov@ispras.ru> (raw)
If sas_domain_attach_transport() fails in aic94xx_init(),
it breaks off initialization, deallocates all resources, but returns zero.
The patch adds -ENOMEM as return value in this case.
Found by Linux Driver Verification project (linuxtesting.org).
