media: usb: uvc: no need to check return value of debugfs_create functions

2020-09-26T08:15:17Z

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Signed-off-by: Greg Kroah-Hartman Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: uvcvideo: Include streaming interface number in debugfs dir name

2019-06-11T16:21:58Z

uvcvideo creates a debugfs directory based on the device bus number and device number. If a device contains more than one uvc function, the creation of the second and following debugfs directories will fail and print an info message like this: "uvcvideo: Unable to create debugfs 3-2 directory." This patch includes the uvc streaming interface number in the debugfs directory name, to make sure it is unique. The directory name format is changed from "-" to "--" Signed-off-by: Torleiv Sundre Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab
