[ Upstream commit cd149eff8d2201a63c074a6d9d03e52926aa535d ] Currently the driver tries to disable the BIOS write protection automatically even if this is not what the user wants. For this reason modify the driver so that by default it does not touch the write protection. Only if specifically asked by the user (setting writeable=1 command line parameter) the driver tries to disable the BIOS write protection.
