Hello Chris,
There is a defect in krealloc with __GFP_ZERO so this code in
drivers/chat/tile-srom.c may not work properly:
drivers/char/tile-srom.c- for (i = 0; ; i++) {
drivers/char/tile-srom.c- int devhdl;
drivers/char/tile-srom.c- char buf[20];
drivers/char/tile-srom.c- struct srom_dev *new_srom_devices =
drivers/char/tile-srom.c- krealloc(srom_devices, (i+1) *
sizeof(struct srom_dev),
drivers/char/tile-srom.c: GFP_KERNEL |
__GFP_ZERO);
drivers/char/tile-srom.c- if (!new_srom_devices) {
drivers/char/tile-srom.c- result = -ENOMEM;
drivers/char/tile-srom.c- goto fail_mem;
drivers/char/tile-srom.c- }
drivers/char/tile-srom.c- srom_devices = new_srom_devices;
