video: udlfb: Fix read EDID timeout

2017-12-20T09:04:57+00:00

[ Upstream commit c98769475575c8a585f5b3952f4b5f90266f699b ] While usb_control_msg function expects timeout in miliseconds, a value of HZ is used. Replace it with USB_CTRL_GET_TIMEOUT and also fix error message which looks like: udlfb: Read EDID byte 78 failed err ffffff92 as error is either negative errno or number of bytes transferred use %d format specifier. Returned EDID is in second byte, so return error when less than two bytes are received. Fixes: 18dffdf8913a ("staging: udlfb: enhance EDID and mode handling support") Signed-off-by: Ladislav Michl Cc: Bernie Thompson Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

video: udlfb: Deletion of unnecessary checks before the function call "vfree"

2014-12-04T14:16:01+00:00

The vfree() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Tomi Valkeinen

video: fbdev: use %*ph specifier to dump small buffers

2014-09-09T11:03:34+00:00

Instead of dereference each byte let's use %*ph specifier in the printk() calls. Signed-off-by: Andy Shevchenko Signed-off-by: Tomi Valkeinen

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.
