Re: [PATCH] e1000e: Use sizeof struct rather than pointer in e1000_get_eeprom()

[Roel Kluin <roel.kluin@gmail.com>]

Don't use the sizeof the pointer to clear the result

No it's probably still not correct, eeprom_buff was kmalloc'd with:

eeprom_buff = kmalloc(sizeof(u16) *
                        (last_word - first_word + 1), GFP_KERNEL);

How about:
