Hi Linus, all,
Coverity uncovered an off-by-one error in the fscpos driver, in function
set_temp_reset(). Writing to the temp3_reset sysfs file will lead to an
array overrun, in turn causing an I2C write to a random register of the
FSC Poseidon chip. Additionally, writing to temp1_reset and temp2_reset
will not work as expected. The fix is straightforward.
This patch is a candidate for 2.6.13 (or 2.6.13.1 if it's too late for
2.6.13.)
Thanks.
