Subject: staging: rtl8192e: rtl92e_get_eeprom_size Fix read size of EPROM_CMD.
From: Malcolm Priestley <tvboxspy@xxxxxxxxx>
commit 90be652c9f157d44b9c2803f902a8839796c090d upstream.
EPROM_CMD is 2 byte aligned on PCI map so calling with rtl92e_readl
will return invalid data so use rtl92e_readw.
The device is unable to select the right eeprom type.
