commit 8460f6003a1d2633737b89c4f69d6f4c0c7c65a3 upstream.

gcc-11 now warns about a confusingly indented code block:

drivers/usb/host/sl811-hcd.c: In function ‘sl811h_hub_control’:
drivers/usb/host/sl811-hcd.c:1291:9: error: this ‘if’ clause does not guard... [-Werror=misleading-indentation]
1291 | if (*(u16*)(buf+2)) /* only if wPortChange is interesting */
| ^~
drivers/usb/host/sl811-hcd.c:1295:17: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘if’
1295 | break;

Rewrite this to use a single if() block with the __is_defined() macro.
