From c0898fca3fce00f824e7f5d48e1edd0900378a03 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 28 Jun 2019 14:16:45 +0200 Subject: drm/selftests: reduce stack usage Putting a large drm_connector object on the stack can lead to warnings in some configuration, such as: drivers/gpu/drm/selftests/test-drm_cmdline_parser.c:18:12: error: stack frame size of 1040 bytes in function 'drm_cmdline_test_res' [-Werror,-Wframe-larger-than=] static int drm_cmdline_test_res(void *ignored) Since the object is never modified, just declare it as 'static const' and allow this to be passed down.
