Andrew, I think this means no one has used the v1 bindings in mainline, so could remove that code? > --- > drivers/char/ipmi/kcs_bmc_aspeed.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/char/ipmi/kcs_bmc_aspeed.c b/drivers/char/ipmi/kcs_bmc_aspeed.c > index 9422d55a0476..a140203c079b 100644 > --- a/drivers/char/ipmi/kcs_bmc_aspeed.c > +++ b/drivers/char/ipmi/kcs_bmc_aspeed.c > @@ -271,7 +271,7 @@ static struct kcs_bmc *aspeed_kcs_probe_of_v1(struct platform_device *pdev) > kcs->ioreg = ast_kcs_bmc_ioregs[channel - 1]; > aspeed_kcs_set_address(kcs, slave); > > - return 0; > + return kcs; > } > > static int aspeed_kcs_calculate_channel(const struct kcs_ioreg *regs) > -- > 2.25.1 >

No, rather Dan's on the ball and it seems I was a bit lax with my testing of the patch. I pinged Corey only the other day regarding the patches; he had been busy and as such hadn't merged them. I have a series to convert our devicetrees over to v2. Now that Corey's taken the patches I can send that and we can get away from v1. Thanks for the fix Dan.

This needs to return the newly allocated struct but instead it returns zero which leads to an immediate Oops in the caller.
