video: move fbdev to drivers/video/fbdev

2014-04-17T05:10:19+00:00

The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.

viafb: reduce viafb_set_iga_path usage

2010-09-24T02:14:48+00:00

The result of viafb_set_iga_path can change after init only in the hotplug ioctl. So we can move it there rather than doing it always when a new mode is set. The setup during init is done via a call from the init chip funtion. This change enables a stable mapping between the old device scheme and a new more powerfull one.

drivers/video/via/ioctl.c: prevent reading uninitialized stack memory

2010-09-15T23:43:53+00:00

The VIAFB_GET_INFO device ioctl allows unprivileged users to read 246 bytes of uninitialized stack memory, because the "reserved" member of the viafb_ioctl_info struct declared on the stack is not altered or zeroed before being copied back to the user. This patch takes care of it. Signed-off-by: Dan Rosenberg Signed-off-by: Florian Tobias Schandinat
