Subject: [PATCH V2 4/9] crypto/nx: Initialize coproc entry with kzalloc
Date: Sat, 29 Feb 2020 03:15:02 -0800 [thread overview]
Message-ID: <1582974902.18705.46.camel@hbabu-laptop> (raw)
In-Reply-To: <1582974266.18705.28.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()
