rt2500usb_validate_eeprom() read data up to 0x6e (EEPROM_CALIBRATE_OFFSET) but only 0x6a bytes has been allocated and read from the eeprom. This lead to out-of-bound accesses and invalid values for EEPROM_BBPTUNE_R17 and EEPROM_CALIBRATE_OFFSET. Change the EEPROM_SIZE to 0x6e in order to retrieve all the fields. Tested with a rt2570 device. Signed-off-by: Adrien Schildknecht <adrien+dev@schischi.me> --- drivers/net/wireless/rt2x00/rt2500usb.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
