Okay, there is a print there. But I am not able to reach to this routine from devm_kzalloc(). devm_kzalloc() <linux/device.h> devm_kmalloc() <drivers/base/devres.c> alloc_dr() <drivers/base/devres.c> kmalloc_track_caller() <linux/slab.h> __kmalloc_track_caller() <mm/slab,slub/slob.c> Taking slab as example: __do_kmalloc() <mm/slab.c> ... I can see cases where NULL is returned after above paths and the function you mentioned wasn't there. So, I am not sure that we will get a print for sure for any error that might occur from devm_kzalloc(). -- To unsubscribe from this list: send the line "unsubscribe linux-pwm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
