Hm... In my version of GCC the error is:
drivers/staging/r8188eu/hal/usb_halinit.c:1870:3: error: a label can only be part of a statement and a declaration is not a statement
That's a different error from what I was expecting. It's caused by
having a declaration directly after a case statement. The warning that
I was expecting was from -Wdeclaration-after-statement and it looks
like this:
warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement]
You really should try investigate why this compiles for you because
something is going wrong. It should not build without a warning.
