libcamera: process: Properly ignore unused result with gcc
Casting the return value of a function to (void) doesn't ignore the unused result warning with gcc. Use a #pragma to fix this properly, to fix compilation with _FORTIFY_SOURCE. Fixes: df23ab95f3d7 ("libcamera: process: fix compilation on Chromium OS") Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com>
