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() Signed-off-by: Haren Myneni <haren@us.ibm.com> --- drivers/crypto/nx/nx-842-powernv.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
