Subject: fbdev: fbmon: fix -Wextra build warnings
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=b5445b244114bf55efa325ea07f417bc5915bc74;p=uclinux-h8%2Flinux.git

fbdev: fbmon: fix -Wextra build warnings

When 'DEBUG' is not defined, modify the DPRINTK() macro to use the
no_printk() macro instead of using <empty>.
This fixes a build warning when -Wextra is used and provides
printk format checking:

../drivers/video/fbdev/core/fbmon.c:812:47: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
../drivers/video/fbdev/core/fbmon.c:842:24: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
