[PATCH 1/2] fbdev: omapfb: avoid -Wempty-body warning

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Arnd Bergmann <arnd@xxxxxxxx>

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.
