[PATCH v3 0/2] Fix slave mode corner issues

From: Liem

Date: Thu Jun 25 2026 - 22:59:10 EST


This series fixes two issues in the i2c-imx slave mode.

Patch 1 clears the slave pointer on registration failure to allow
subsequent re-registration.

Patch 2 cancels the hrtimer before clearing the slave pointer during
unregistration, preventing a potential use-after-free / NULL pointer
dereference.

Changes in v3:
- Split the original patch into two separate patches as suggested by
Frank Li.
- v2: https://lore.kernel.org/imx/
20260625160219.55116-1-liem16213@xxxxxxxxx/

Liem (2):
i2c: imx: Clear slave pointer on registration error
i2c: imx: Cancel hrtimer before clearing slave pointer
