adf_dev_aer_schedule_reset() is never called in atomic context, as it calls wait_for_completion_timeout(). adf_dev_aer_schedule_reset() calls kzalloc() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself. I also manually check the kernel code before reporting it.
