Signed-off-by: Nicholas Mc Guire --- Only the timeout case was being handled, the signal case (-ERESTARTSYS) was treated just like the case of successful completion, which is most likely not reasonable. The callsite for p54p_open() in p54p_firmware_step2() expect !=0 to indicate error so both -ERESTARTSYS and -ETIMEDOUT should be fine for the current handling.
