Subject: fbdev: fbmon: fix -Wextra build warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: b5445b244114bf55efa325ea07f417bc5915bc74
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

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:
