Subject: [PATCH 5/6] fbdev: pm[23]fb.c: fix -Wextra build warnings and errors
Date: Sat, 14 Mar 2020 21:10:01 -0700	[thread overview]
Message-ID: <20200315041002.24473-6-rdunlap@infradead.org> (raw)
In-Reply-To: <20200315041002.24473-1-rdunlap@infradead.org>

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);

Alternative: use pr_debug() so that CONFIG_DYNAMIC_DEBUG can be used
at these sites.
