[lvc-project] [PATCH net 0/3] e1000/e1000e: fix uninitialized memory access in EEPROM write

[Agalakov Daniil]

This series addresses a common issues related to uninitialized memory
access during EEPROM write operations in the e1000 and e1000e drivers.

In the e1000 driver, the return value of e1000_read_eeprom() was not
checked, and both e1000 and e1000e drivers performed endianness
conversion on the entire buffer, including uninitialized interior words.

The changes are:
 - add missing error checks for e1000_read_eeprom() in e1000;
 - limit endianness conversion to the boundary words being read,
   avoiding a loop over entire (and partially uninitialized) buffer in
   both e1000 and e1000e.

Patch 1: e1000: check return value of e1000_read_eeprom
Patch 2: e1000: fix endianness conversion of uninitialized words
Patch 3: e1000e: fix endianness conversion of uninitialized words
