[U-Boot] Bombs away! Was: [PATCH 02/10] net: rtl8139: Add initialized eth_device structure

Dear All,

dev = (struct eth_device *)malloc(sizeof *dev);

• memset(dev, 0, sizeof(*dev));
  
  

  sprintf (dev->name, "RTL8139#%d", card_number);

Apparently its quite common NOT to check malloc()'s possible NULL return value... At least most NET drivers don't seem to...

Maybe another RFC to avoid duplicating code:

malloc_cleared_panic() to allocate and clear memory for a really required structure and put a proper panic message if that fails. Assuming that continuing u-boot once a driver cannot even be initialized is futile, that would save even more code in each driver.
