When 'DEBUG' is not defined, modify the DPRINTK() macro to use the no_printk() macro instead of using <empty>. This fixes build warnings when -Wextra is used and provides printk format checking:
../drivers/video/fbdev/pm2fb.c:227:38: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body] ../drivers/video/fbdev/pm3fb.c:1039:33: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
Also drop one argument in two DPRINTK() macro uses to provide the correct number of arguments and use the correct field in one case to fix a build error:
../drivers/video/fbdev/pm3fb.c:353:9: error: ‘struct fb_info’ has no member named ‘current_par’ info->current_par->depth);
