Building with 'make W=1' shows a few harmless warnings:
drivers/video/fbdev/omap2/omapfb/omapfb-main.c: In function 'omapfb_calc_addr':
drivers/video/fbdev/omap2/omapfb/omapfb-main.c:823:56: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
823 | var->xoffset, var->yoffset, offset);
| ^
drivers/video/fbdev/omap2/omapfb/omapfb-ioctl.c: In function 'omapfb_ioctl':
drivers/video/fbdev/omap2/omapfb/omapfb-ioctl.c:911:45: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
911 | DBG("ioctl failed: %d\n", r);
Avoid these by using no_printk(), which adds format string checking as
well.
