platform/x86: sony-laptop: Fix unintentional fall-through
It seems that the default case should return AE_CTRL_TERMINATE, instead of falling through to case ACPI_RESOURCE_TYPE_END_TAG and returning AE_OK; otherwise the line of code at the end of the function is unreachable and makes no sense: return AE_CTRL_TERMINATE; This fix is based on the following thread of discussion: https://lore.kernel.org/patchwork/patch/959782/ Fixes: 33a04454527e ("sony-laptop: Add SNY6001 device handling (sonypi reimplementation)") Cc: stable@vger.kernel.org Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com> Reviewed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
