Checking the values as they're parsed should prevent this. Changes in v3: - Squash patches changing miic_port_max - Change name of miic_port_max to miic_port_last - Remove fixes tags - Add another check for configuration value of miic-switch-portin - Link to v2: https://lore.kernel.org/r/20260928-miic-validate-dtb-v2-0-1ee3d33748e9@reliablecontrols.com/ Changes in v2: - Simplify fixes by making miic_port_max the last documented port number - Add fixes tags - Link to v1: https://lore.kernel.org/r/20260925-miic-validate-dtb-v1-0-3a6db9bb75ec@reliablecontrols.com Signed-off-by: Kyle Hendry --- Kyle Hendry (2): net: pcs: rzn1-miic: Update port numbering for RZ/T2H net: pcs: rzn1-miic: Validate dtb configuration values drivers/net/pcs/pcs-rzn1-miic.c | 45 +++++++++++++++++++++++++++++++++-------- 1 file changed, 37 insertions(+), 8 deletions(-) --- base-commit: a5e7d8e446af9803e37a3b6a4d416fb41178348f change-id: 20261005-miic-validate-dtb-v3-cf31820cb1e9 Best regards, -- Kyle Hendry
