Also, you don't allocate chip->valid_mask anywhere.
So I see now where it's allocated, but something is fishy. I have three TLMMs on my chip: [ 67.107018] gpiochip_init_valid_mask:351 gpiochip->need_valid_mask=1 [ 67.153747] gpiochip_init_valid_mask:356 gpiochip->ngpio=72 [ 67.195324] gpiochip_init_valid_mask:361 gpiochip->valid_mask=0000000070b1a4b6 [ 68.532992] gpiochip_init_valid_mask:356 gpiochip->ngpio=44 [ 68.574496] gpiochip_init_valid_mask:361 gpiochip->valid_mask=000000002f33b8a3 [ 68.709378] msm_gpio_init_valid_mask:837 ret=44 max_gpios=44 chip->valid_mask=000000002f33b8a3 [ 69.726502] gpiochip_init_valid_mask:351 gpiochip->need_valid_mask=1 [ 69.772960] gpiochip_init_valid_mask:356 gpiochip->ngpio=54 [ 69.814084] gpiochip_init_valid_mask:361 gpiochip->valid_mask=000000001a53c932 Are these normal addresses for kcalloc() to return? They're not even word-aligned. -- Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.
