ANSIfy prototypes in subr_usbd.c.
Clang generates the following warnings when building subr_usbd.c:
| subr_usbd.c:598:13: warning: promoted type 'int' of K&R function |
| parameter is not compatible with the parameter type 'uint8_t' (aka |
| 'unsigned char') declared in a previous prototype |
| subr_usbd.c:627:13: warning: promoted type 'int' of K&R function |
| parameter is not compatible with the parameter type 'uint8_t' (aka |
| 'unsigned char') declared in a previous prototype |
| subr_usbd.c:649:13: warning: promoted type 'int' of K&R function |
| parameter is not compatible with the parameter type 'uint8_t' (aka |
| 'unsigned char') declared in a previous prototype |
Instead of just ANSIfying these three prototypes, do it for the entire
file.
