Franck LENORMAND f75484a0b8 firmware: imx: scu: Fix corruption of header ... [ Upstream commit f5f27b79eab80de0287c243a22169e4876b08d5e ] The header of the message to send can be changed if the response is longer than the request: - 1st word, the header is sent - the remaining words of the message are sent - the response is received asynchronously during the execution of the loop, changing the size field in the header - the for loop test the termination condition using the corrupted header It is the case for the API build_info which has just a header as request but 3 words in response. This issue is fixed storing the header locally instead of using a pointer on it.
