| |
Only allocate up to USBG_NUM_CMDS number of session tags. We should not be using more than USBG_NUM_CMDS of tags due to the number of commands limit we imposed. Each command uses a unique tag. Any more than that is unnecessary. By limitting it, we can detect an issue in our driver immediately should we run out of session tags.
