If anyone has any objections, please let me know. ------------------ From: Pengpeng Hou commit 7dc4de2aa6316f1d044cde21f5acfec5f3ec6b47 upstream. devm_gpiod_get_optional() returns NULL when the optional GPIO is absent, but returns an ERR_PTR when the GPIO provider lookup fails, including probe deferral. Probe currently logs the ERR_PTR case as if the reset GPIO were simply absent and keeps the error pointer in reset_gpio. Later ads124s_reset() treats any non-NULL reset_gpio as a valid descriptor and passes it to gpiod_set_value_cansleep(). Return the lookup error instead of retaining the ERR_PTR.
