[ Upstream commit cecf7560f00a8419396a2ed0f6e5d245ccb4feac ] clang static analysis reports this representative problem applesmc.c:758:10: warning: 1st function call argument is an uninitialized value left = be16_to_cpu(*(__be16 *)(buffer + 6)) >> 2; ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ buffer is filled by the earlier call ret = applesmc_read_key(LIGHT_SENSOR_LEFT_KEY, ... This problem is reported because a goto skips the status check. Other similar problems use data from applesmc_read_key before checking the status. So move the checks to before the use.

README
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
