[PATCH] drivers: staging: media: go7007: go7007-usb.c use pr_*() instead of dev_*() before 'go' initialized in go7007_usb_probe()

[Chen Gang]

dev_*() assumes 'go' is already initialized, so need use pr_*() instead
of before 'go' initialized. Related warning (with allmodconfig under
hexagon):

    CC [M]  drivers/staging/media/go7007/go7007-usb.o
  drivers/staging/media/go7007/go7007-usb.c: In function 'go7007_usb_probe':
  drivers/staging/media/go7007/go7007-usb.c:1060:2: warning: 'go' may be used uninitialized in this function [-Wuninitialized]

Also remove useless code after 'return' statement.

pr_devel is commonly compiled out completely unless DEBUG is #defined.
You probably want to use pr_debug here.

This should all be fixed in my staging-linus branch already, right?  No
need for this anymore from what I can tell, sorry.

That's all right (in fact don't need sorry).  :-)

And excuse me, I am not quite familiar upstream kernel version merging
and branches. Is it still better/suitable/possible to sync some bug fix
patches from staging brach to next brach?


Thanks.
