From ec1c20b02ae0bdce82b54b1b8a1e72e86d45f672 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sun, 6 Dec 2020 20:02:46 +0100 Subject: video: fbdev: controlfb: Fix set but not used warnings [ Upstream commit 4aca4dbcac9d8eed8a8dc15b6883270a20a84218 ] The controlfb driver has a number of dummy defines for IO operations. They were introduced in commit a07a63b0e24d ("video: fbdev: controlfb: add COMPILE_TEST support"). The write variants did not use their value parameter in the dummy versions, resulting in set but not used warnings. Fix this by adding "(void)val" to silence the compiler.
