4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
commit 484c7bbf2649831714da3a0fa30213977458e9b5 upstream.
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.
