Patch

===============

[ Upstream commit 484c7bbf2649831714da3a0fa30213977458e9b5 ]

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.
