Sure, no problem. Thanks. To be clear I'm applying these to my 5.10.32 linux-fslc kernel built from Yocto/meta-freescale Hardknott in case any of that matters. Full disclosure. I was able to do a git clone of your repo with --depth 1 but the --single-branch thing didn't work for me ... yet. Keep getting getting "remote hung up etc." Will try again. > > -----------------------------[ cut here ]----------------------------- From > ccfe702efa0c4d19d631fc58ed83a765077e4a62 Mon Sep 17 00:00:00 2001 > From: Vladimir Oltean <vladimir.olt...@nxp.com> > Date: Tue, 19 Oct 2021 00:21:34 +0300 > Subject: [PATCH] net: dsa: ksz9477: fix ksz_port dereference from > ksz9477_port_deferred_xmit > > The previous patch left an incorrect dereference of struct ksz_port. > That's not how we get it, dp->priv points to a different structure. > > Signed-off-by: Vladimir Oltean <vladimir.olt...@nxp.com> > --- > drivers/net/dsa/microchip/ksz9477_ptp.c | 4 +++- > 1 file changed, 3 insertions(+), 1 deletion(-) > > diff --git a/drivers/net/dsa/microchip/ksz9477_ptp.c > b/drivers/net/dsa/microchip/ksz9477_ptp.c > index 0f05aafbdd3d..fb4f89efd9cd 100644 > --- a/drivers/net/dsa/microchip/ksz9477_ptp.c > +++ b/drivers/net/dsa/microchip/ksz9477_ptp.c > @@ -762,7 +762,9 @@ static void ksz9477_port_deferred_xmit(struct > kthread_work *work) > struct sk_buff *skb = xmit_work->skb; > struct dsa_port *dp = xmit_work->dp; > struct ksz_device *dev = ds->priv; > - struct ksz_port *prt = dp->priv; > + struct ksz_port *prt; > + > + prt = &dev->ports[dp->index]; > > reinit_completion(&prt->tstamp_completion); > > -----------------------------[ cut here ]----------------------------- CONFIDENTIALITY NOTICE: This email and any attachments are for the sole use of the intended recipient and may contain material that is proprietary, confidential, privileged or otherwise legally protected or restricted under applicable government laws.
