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@gmail.com/ Liem (2): i2c: imx: Clear slave pointer on registration error i2c: imx: Cancel hrtimer before clearing slave pointer drivers/i2c/busses/i2c-imx.c | 2 ++ 1 file changed, 2 insertions(+) -- 2.34.1
