[PATCH] fbdev: via: remove possibly unused variables
From: Arnd Bergmann <arnd@arndb.de>
Date: 2017-05-16 11:29:17
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.
