Subject: [PATCH 04/10] crypto/nx: Initialize coproc entry with kzalloc
Date: Sun, 15 Dec 2019 05:02:06 -0800 [thread overview]
Message-ID: <1576414926.16318.4084.camel@hbabu-laptop> (raw)
In-Reply-To: <1576414240.16318.4066.camel@hbabu-laptop>
coproc entry is initialized during NX probe on power9, but not on P8.
nx842_delete_coprocs() is used for both and frees receive window if it
is allocated. Getting crash for rmmod on P8 since coproc->vas.rxwin
is not initialized.
This patch replaces kmalloc with kzalloc in nx842_powernv_probe()
