before this change, you got:
0 Target : <0x0000470c> { _dump_stack + 0x0 }
Source : <0x00005dd0> { _cmp_label + 0x58 }
1 Target : <0x00005dd0> { _cmp_label + 0x58 }
Source : <0x00005d84> { _cmp_label + 0xc }
2 Target : <0x00005d78> { _cmp_label + 0x0 }
Source : <0x00005fd4> { _gpio_request + 0x14 }
3 Target : <0x00005fc0> { _gpio_request + 0x0 }
Source : <0x00184128> { _bfin_nand_init + 0x54 }
4 Target : <0x00184118> { _bfin_nand_init + 0x44 }
Now with this change - you will see a dump of printk.
Any objections with :
dump_stack();
printk(KERN_ERR"Please provide none-null label\n");
