Subject: [PATCH v3 4/9] crypto/nx: Initialize coproc entry with kzalloc
Date: Fri, 06 Mar 2020 16:34:12 -0800	[thread overview]
Message-ID: <1583541252.9256.38.camel@hbabu-laptop> (raw)
In-Reply-To: <1583540877.9256.24.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()
