Subject: [PATCH v4 4/9] crypto/nx: Initialize coproc entry with kzalloc
Date: Sun, 22 Mar 2020 21:03:00 -0700	[thread overview]
Message-ID: <1584936180.9256.15326.camel@hbabu-laptop> (raw)
In-Reply-To: <1584934879.9256.15321.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()
