From 458025f6c16188a9f28219578448fac24b2cd487 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 22 Mar 2021 11:53:00 +0100 Subject: vgaarb: avoid -Wempty-body warnings Building with W=1 shows a few warnings for an empty macro: drivers/gpu/drm/qxl/qxl_drv.c: In function 'qxl_pci_probe': drivers/gpu/drm/qxl/qxl_drv.c:131:50: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body] 131 | vga_put(pdev, VGA_RSRC_LEGACY_IO); | ^ drivers/gpu/drm/qxl/qxl_drv.c: In function 'qxl_pci_remove': drivers/gpu/drm/qxl/qxl_drv.c:159:50: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body] 159 | vga_put(pdev, VGA_RSRC_LEGACY_IO); Change this to an inline function to make it more robust and avoid the warning.
