Subject: [PATCH v5 4/9] crypto/nx: Initialize coproc entry with kzalloc
Date: Wed, 01 Apr 2020 15:04:55 -0700 [thread overview]
Message-ID: <1585778695.2275.0.camel@hbabu-laptop> (raw)
In-Reply-To: <1585777592.10664.462.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()
