No...  You've just changed error handling to success handling and added
some new indent levels and made a tangled spaghetti exit path even more
tangled.  Spoderman wants to know, "Why u do dis?"

It should look like:

diff --git a/drivers/staging/rtl8188eu/os_dep/usb_intf.c b/drivers/staging/rtl8188eu/os_dep/usb_intf.c

See?  No indenting, no if statements.  Just one statement after another.
