Commit 60d2fa0dad06 ("fbdev: omap2: no need to check return value of debugfs_create functions") changed the declaration of the return value of function dss_debugfs_create_file() and the following two warnings appeared: drivers/video/fbdev/omap2/omapfb/dss/core.c: In function ‘dss_debugfs_create_file’: drivers/video/fbdev/omap2/omapfb/dss/core.c:139:9: warning: ‘return’ with a value, in function returning void return 0; ^ drivers/video/fbdev/omap2/omapfb/dss/core.c: In function ‘omap_dss_probe’: drivers/video/fbdev/omap2/omapfb/dss/core.c:172:6: warning: unused variable ‘r’ [-Wunused-variable] int r; ^ Rework so function dss_debugfs_create_file() that is declared to return void don't 'return 0' and remove the declaration of the unused variable 'r'.
