From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Date: Tue, 16 May 2017 11:28:57 +0000 Subject: [PATCH] fbdev: via: remove possibly unused variables Message-Id: <20170516112906.4144714-1-arnd@arndb.de> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Florian Tobias Schandinat , Bartlomiej Zolnierkiewicz Cc: Arnd Bergmann , linux-fbdev@vger.kernel.org, linux-kernel@vger.kernel.org When CONFIG_PROC_FS is disabled, we get warnings about unused variables as remove_proc_entry() evaluates to an empty macro. drivers/video/fbdev/via/viafbdev.c: In function 'viafb_remove_proc': drivers/video/fbdev/via/viafbdev.c:1635:4: error: unused variable 'iga2_entry' [-Werror=unused-variable] drivers/video/fbdev/via/viafbdev.c:1634:4: error: unused variable 'iga1_entry' [-Werror=unused-variable] These are easy to avoid by using the pointer from the structure.
