Subject: [PATCH 2/6] fbdev: aty: fix -Wextra build warning
Date: Sat, 14 Mar 2020 21:09:58 -0700	[thread overview]
Message-ID: <20200315041002.24473-3-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 a build warning when -Wextra is used and provides
printk format checking:

../drivers/video/fbdev/aty/atyfb_base.c:784:61: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]

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