hi,i will fix it like below: par->gpio.te = devm_gpiod_get_index_optional(dev, "te", 0, GPIOD_IN); if (IS_ERR(par->gpio.te)) { rc = PTR_ERR(par->gpio.te); pr_err("Failed to request te gpio: %d\n", rc); par->gpio.te = NULL; }
I wish you would just copy and paste the code that I sent you instead, but this also fixes the crash...
While this fixes the crash, it does not propagate the error condition (which may be -EPROBE_DEFER) upstream. Same for devm_request_irq().
